Gets the built-in type kind for this .
A object that represents the built-in type kind for this
.
Gets a value indicating whether this can have a null value.
Nullability in the conceptual model and store model is a simple indication of whether or not
the property is considered nullable. Nullability in the object model is more complex.
When using convention based mapping (as usually happens with POCO entities), a property in the
object model is considered nullable if and only if the underlying CLR type is nullable and
the property is not part of the primary key.
When using attribute based mapping (usually used with entities that derive from the EntityObject
base class), a property is considered nullable if the IsNullable flag is set to true in the
attribute. This flag can
be set to true even if the underlying type is not nullable, and can be set to false even if the
underlying type is nullable. The latter case happens as part of default code generation when
a non-nullable property in the conceptual model is mapped to a nullable CLR type such as a string.
In such a case, the Entity Framework treats the property as non-nullable even though the CLR would
allow null to be set.
There is no good reason to set a non-nullable CLR type as nullable in the object model and this
should not be done even though the attribute allows it.

Identifies the kind of a relationship
The relationship is an Association
Container for the lazily created relationship navigation
property objects (collections and refs).
Creates a new object.
Used by data classes that support relationships. If the change tracker
requests the RelationshipManager property and the data class does not
already have a reference to one of these objects, it calls this method
to create one, then saves a reference to that object. On subsequent accesses
to that property, the data class should return the saved reference.
The reason for using a factory method instead of a public constructor is to
emphasize that this is not something you would normally call outside of a data class.
By requiring that these objects are created via this method, developers should
give more thought to the operation, and will generally only use it when
they explicitly need to get an object of this type. It helps define the intended usage.

Takes an existing EntityReference that was created with the default constructor and initializes it using the provided relationship and target role names.
This method is designed to be used during deserialization only, and will throw an exception if the provided EntityReference has already been initialized,

instances.
The serialized stream.
This class contains the common methods need for an date object.
Public constant name used for change tracking
Providing this definition allows users to use this constant instead of
hard-coding the string. This helps to ensure the property name is correct
and allows faster comparisons in places where we are looking for this specific string.
Users can still use the case-sensitive string directly instead of the constant,
it will just be slightly slower on comparison.
Including the dash (-) character around the name ensures that this will not conflict with
a real data property, because -EntityKey- is not a valid identifier name
Notification that a property has been changed.

object have changed by using either a null reference
(Nothing in Visual Basic) or String.Empty as the property name
in the PropertyChangedEventArgs.

Asynchronously executes a query directly against the data source and returns a sequence of typed results.
The query is specified using the server's native query language, such as SQL.
Results are not tracked by the context, use the overload that specifies an entity set name to track results.
As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter.
context.ExecuteStoreQueryAsync<Post>("SELECT * FROM dbo.Posts WHERE Author = @p0", userSuppliedAuthor);
Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string.
context.ExecuteStoreQueryAsync<Post>("SELECT * FROM dbo.Posts WHERE Author = @author", new SqlParameter("@author", userSuppliedAuthor));
Multiple active operations on the same context instance are not supported. Use 'await' to ensure
that any asynchronous operations have completed before calling another method on this context.
The element type of the result sequence.
The query specified in the server's native query language.
The options for executing this query.
The parameter values to use for the query. If output parameters are used, their values will not be
available until the results have been read completely. This is due to the underlying behavior
of DbDataReader, see http://go.microsoft.com/fwlink/?LinkID=398589 for more details.

objects, Refresh original values with store value, keeping all values on client
object. The next time an update happens, all the client change units will be
considered modified and require updating.
Discard all changes on the client and refresh values with store values.
Client original values is updated to match the store.
Flags used to modify behavior of ObjectContext.SaveChanges()
Changes are saved without the DetectChanges or the AcceptAllChangesAfterSave methods being called.
After changes are saved, the AcceptAllChangesAfterSave method is called, which resets change tracking in the ObjectStateManager.
Before changes are saved, the DetectChanges method is called to synchronize the property values of objects that are attached to the object context with data in the ObjectStateManager.
This exception is thrown when a update operation violates the concurrency constraint.

Used for conversion between different representations of bit array.
Returns (n+(div-1))/div, rearranged to avoid arithmetic overflow.
For example, in the bit to int case, the straightforward calc would
be (n+31)/32, but that would cause overflow. So instead it's
rearranged to ((n-1)/32) + 1, with special casing for 0.
Usage:
GetArrayLength(77, BitsPerInt32): returns how many ints must be
allocated to store 77 bits.

An instance of this class is obtained from an object and can be used
to manage the actual database backing a DbContext or connection.
This includes creating, deleting, and checking for the existence of a database.
Note that deletion and checking for existence of a database can be performed using just a
connection (i.e. without a full context) by using the static methods of this class.
Gets the transaction the underlying store connection is enlisted in. May be null.
Enables the user to pass in a database transaction created outside of the object
if you want the Entity Framework to execute commands within that external transaction.
Alternatively, pass in null to clear the framework's knowledge of that transaction.

Sets the database initializer to use for the given context type. The database initializer is called when a
the given type is used to access a database for the first time.
The default strategy for Code First contexts is an instance of .
The type of the context.
The initializer to use, or null to disable initialization for the given context type.
Runs the registered on this context.
If "force" is set to true, then the initializer is run regardless of whether or not it
has been run before. This can be useful if a database is deleted while an app is running
and needs to be reinitialized.
If "force" is set to false, then the initializer is only run if it has not already been
run for this context, model, and connection in this app domain. This method is typically
used when it is necessary to ensure that the database has been created and seeded
before starting some operation where doing so lazily will cause issues, such as when the
operation is part of a transaction.
If set to true the initializer is run even if it has already been run.
Checks whether or not the database is compatible with the current Code First model.
Model compatibility currently uses the following rules.
If the context was created using either the Model First or Database First approach then the
model is assumed to be compatible with the database and this method returns true.
For Code First the model is considered compatible if the model is stored in the database
in the Migrations history table and that model has no differences from the current model as
determined by Migrations model differ.
If the model is not stored in the database but an EF 4.1/4.2 model hash is found instead,
then this is used to check for compatibility.
If set to true then an exception will be thrown if no model metadata is found in the database. If set to false then this method will return true if metadata is not found.
True if the model hash in the context and the database match; false otherwise.
Creates a new database on the database server for the model defined in the backing context.
Note that calling this method before the database initialization strategy has run will disable
executing that strategy.
Creates a new database on the database server for the model defined in the backing context, but only
if a database with the same name does not already exist on the server.
True if the database did not exist and was created; false otherwise.
Checks whether or not the database exists on the server.
True if the database exists; false otherwise.
Deletes the database on the database server if it exists, otherwise does nothing.
Calling this method from outside of an initializer will mark the database as having
not been initialized. This means that if an attempt is made to use the database again
after it has been deleted, then any initializer set will run again and, usually, will
try to create the database again automatically.
True if the database did exist and was deleted; false otherwise.
Checks whether or not the database exists on the server.
The connection to the database is created using the given database name or connection string
in the same way as is described in the documentation for the class.
The database name or a connection string to the database.
True if the database exists; false otherwise.
Deletes the database on the database server if it exists, otherwise does nothing.

in the same way as is described in the documentation for the class.
The database name or a connection string to the database.
True if the database did exist and was deleted; false otherwise.
Checks whether or not the database exists on the server.
An existing connection to the database.
True if the database exists; false otherwise.
Deletes the database on the database server if it exists, otherwise does nothing.
An existing connection to the database.
True if the database did exist and was deleted; false otherwise.
The connection factory to use when creating a from just
a database name or a connection string.
This is used when just a database name or connection string is given to or when
the no database name or connection is given to DbContext in which case the name of
the context class is passed to this factory in order to generate a DbConnection.
By default, the instance to use is read from the application's .config
file from the "EntityFramework DefaultConnectionFactory" entry in appSettings. If no entry is found in
the config file then is used. Setting this property in code
always overrides whatever value is found in the config file.
Creates a raw SQL query that will return elements of the given generic type.
The type can be any type that has properties that match the names of the columns returned
from the query, or can be a simple primitive type. The type does not have to be an
entity type. The results of this query are never tracked by the context even if the
type of object returned is an entity type. Use the
method to return entities that are tracked by the context.
As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter.
context.Database.SqlQuery<Post>("SELECT * FROM dbo.Posts WHERE Author = @p0", userSuppliedAuthor);
Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string.

A class derived from this class can be placed in the same assembly as a class derived from
to define Entity Framework configuration for an application.
Configuration is set by calling protected methods and setting protected properties of this
class in the constructor of your derived type.
The type to use can also be registered in the config file of the application.
See http://go.microsoft.com/fwlink/?LinkId=260883 for more information about Entity Framework configuration.
Any class derived from must have a public parameterless constructor
and that constructor should call this constructor.

A type to use for configuration discovery.
Attempts to discover and load the from the given assembly.
This method is intended to be used by tooling to ensure that the correct configuration is loaded into
the app domain. Tooling should use this method before accessing the
property. If the tooling knows the type being used, then the
method should be used since it gives a greater chance that
the correct configuration will be found.
An to use for configuration discovery.
Occurs during EF initialization after the DbConfiguration has been constructed but just before
it is locked ready for use. Use this event to inspect and/or override services that have been
registered before the configuration is locked. Note that this event should be used carefully
since it may prevent tooling from discovering the same configuration that is used at runtime.
Handlers can only be added before EF starts to use the configuration and so handlers should
generally be added as part of application initialization. Do not access the DbConfiguration
static methods inside the handler; instead use the members of
to get current services and/or add overrides.
Call this method from the constructor of a class derived from to
add a instance to the Chain of Responsibility of resolvers that
are used to resolve dependencies needed by the Entity Framework.
Resolvers are asked to resolve dependencies in reverse order from which they are added. This means
that a resolver can be added to override resolution of a dependency that would already have been
resolved in a different way.
The exceptions to this is that any dependency registered in the application's config file
will always be used in preference to using a dependency resolver added here.

This attribute can be placed on a subclass of to indicate that the subclass of
representing the code-based configuration for the application is in a different
assembly than the context type.
Normally a subclass of should be placed in the same assembly as
the subclass of used by the application. It will then be discovered automatically.
However, if this is not possible or if the application contains multiple context types in different
assemblies, then this attribute can be used to direct DbConfiguration discovery to the appropriate type.
An alternative to using this attribute is to specify the DbConfiguration type to use in the application's
config file. See http://go.microsoft.com/fwlink/?LinkId=260883 for more information.

A DbContext instance represents a combination of the Unit Of Work and Repository patterns such that
it can be used to query from a database and group together changes that will then be written
back to the store as a unit.
DbContext is conceptually similar to ObjectContext.
DbContext is usually used with a derived type that contains properties for
the root entities of the model. These sets are automatically initialized when the
instance of the derived class is created. This behavior can be modified by applying the
attribute to either the entire derived context
class, or to individual properties on the class.
The Entity Data Model backing the context can be specified in several ways. When using the Code First
approach, the properties on the derived context are used to build a model
by convention. The protected OnModelCreating method can be overridden to tweak this model. More
control over the model used for the Model First approach can be obtained by creating a
explicitly from a and passing this model to one of the DbContext constructors.
When using the Database First or Model First approach the Entity Data Model can be created using the
Entity Designer (or manually through creation of an EDMX file) and then this model can be specified using
entity connection string or an object.
The connection to the database (including the name of the database) can be specified in several ways.
If the parameterless DbContext constructor is called from a derived context, then the name of the derived context
is used to find a connection string in the app.config or web.config file. If no connection string is found, then
the name is passed to the DefaultConnectionFactory registered on the class. The connection
factory then uses the context name as the database name in a default connection string. (This default connection
string points to (localdb)\MSSQLLocalDB unless a different DefaultConnectionFactory is registered.)
Instead of using the derived context name, the connection/database name can also be specified explicitly by
passing the name to one of the DbContext constructors that takes a string. The name can also be passed in
the form "name=myname", in which case the name must be found in the config file or an exception will be thrown.
Note that the connection found in the app.config or web.config file can be a normal database connection
string (not a special Entity Framework connection string) in which case the DbContext will use Code First.
However, if the connection found in the config file is a special Entity Framework connection string, then the
DbContext will use Database/Model First and the model specified in the connection string will be used.
An existing or explicitly created DbConnection can also be used instead of the database/connection name.
A can be applied to a class derived from DbContext to set the
version of conventions used by the context when it creates a model. If no attribute is applied then the
latest version of conventions will be used.
Constructs a new context instance using conventions to create the name of the database to
which a connection will be made. The by-convention name is the full name (namespace + class name)
of the derived context class.
See the class remarks for how this is used to create a connection.

This method is called when the model for a derived context has been initialized, but
before the model has been locked down and used to initialize the context. The default
implementation of this method does nothing, but it can be overridden in a derived class
such that the model can be further configured before it is locked down.
Typically, this method is called only once when the first instance of a derived context
is created. The model for that context is then cached and is for all further instances of
the context in the app domain. This caching can be disabled by setting the ModelCaching
property on the given ModelBuilder, but note that this can seriously degrade performance.
More control over caching is provided through use of the DbModelBuilder and DbContextFactory
classes directly.
The builder that defines the model for the context being created.
Creates a Database instance for this context that allows for creation/deletion/existence checks
for the underlying database.
Returns a instance for access to entities of the given type in the context
and the underlying store.
Note that Entity Framework requires that this method return the same instance each time that it is called
for a given context instance and entity type. Also, the non-generic returned by the
method must wrap the same underlying query and set of entities. These invariants must
be maintained if this method is overridden for anything other than creating test doubles for unit testing.
See the class for more details.

DbModelBuilder is used to map CLR classes to a database schema.
This code centric approach to building an Entity Data Model (EDM) model is known as 'Code First'.
DbModelBuilder is typically used to configure a model by overriding
DbContext.OnModelCreating(DbModelBuilder)
.
You can also use DbModelBuilder independently of DbContext to build a model and then construct a
or .
The recommended approach, however, is to use OnModelCreating in as
the workflow is more intuitive and takes care of common tasks, such as caching the created model.
Types that form your model are registered with DbModelBuilder and optional configuration can be
performed by applying data annotations to your classes and/or using the fluent style DbModelBuilder
API.
When the Build method is called a set of conventions are run to discover the initial model.
These conventions will automatically discover aspects of the model, such as primary keys, and
will also process any data annotations that were specified on your classes. Finally
any configuration that was performed using the DbModelBuilder API is applied.
Configuration done via the DbModelBuilder API takes precedence over data annotations which
in turn take precedence over the default conventions.
Initializes a new instance of the class.
The process of discovering the initial model will use the set of conventions included
in the most recent version of the Entity Framework installed on your machine.
Upgrading to newer versions of the Entity Framework may cause breaking changes
in your application because new conventions may cause the initial model to be
configured differently. There is an alternate constructor that allows a specific
version of conventions to be specified.
Initializes a new instance of the class that will use
a specific set of conventions to discover the initial model.

This method is provided as a convenience to allow entity types to be registered dynamically
without the need to use MakeGenericMethod in order to call the normal generic Entity method.
This method does not allow further configuration of the entity type using the fluent APIs since
these APIs make extensive use of generic type parameters.

configure the complex type. This method can be called multiple times for the same type to
perform multiple lines of configuration.
The type to be registered or configured.

A value from this enumeration can be provided directly to the
class or can be used in the applied to
a class derived from . The value used defines which version of
the DbContext and DbModelBuilder conventions should be used when building a model from
code--also known as "Code First".
Using DbModelBuilderVersion.Latest ensures that all the latest functionality is available
when upgrading to a new release of the Entity Framework. However, it may result in an
application behaving differently with the new release than it did with a previous release.
This can be avoided by using a specific version of the conventions, but if a version
other than the latest is set then not all the latest functionality will be available.
Indicates that the latest version of the and
conventions should be used.
Indicates that the version of the and
conventions shipped with Entity Framework v4.1
should be used.
Indicates that the version of the and
conventions shipped with Entity Framework v5.0

conventions shipped with Entity Framework v6.0
should be used.
This attribute can be applied to a class derived from to set which
version of the DbContext and conventions should be used when building
a model from code--also known as "Code First". See the
enumeration for details about DbModelBuilder versions.
If the attribute is missing from DbContextthen DbContext will always use the latest
version of the conventions. This is equivalent to using DbModelBuilderVersion.Latest.

test double must be implemented by the test double except AsNoTracking, AsStreaming, an Include where
the default implementation is a no-op.
Finds an entity with the given primary key values.
If an entity with the given primary key values exists in the context, then it is
returned immediately without making a request to the store. Otherwise, a request
is made to the store for an entity with the given primary key values and this entity,
if found, is attached to the context and returned. If no entity is found in the
context or the store, then null is returned.
The ordering of composite key values is as defined in the EDM, which is in turn as defined in
the designer, by the Code First fluent API, or by the DataMember attribute.
The values of the primary key for the entity to be found.
The entity found, or null.
Thrown if multiple entities exist in the context with the primary key values given.
Thrown if the type of entity is not part of the data model for this context.
Thrown if the types of the key values do not match the types of the key values for the entity type to be found.
Thrown if the context has been disposed.

Gets an that represents a local view of all Added, Unchanged,
and Modified entities in this set. This local view will stay in sync as entities are added or
removed from the context. Likewise, entities added to or removed from the local view will automatically
be added to or removed from the context.
This property can be used for data binding by populating the set with data, for example by using the Load
extension method, and then binding to the local data through this property. For WPF bind to this property
directly. For Windows Forms bind to the result of calling ToBindingList on this property
The local view.
Attaches the given entity to the context underlying the set. That is, the entity is placed
into the context in the Unchanged state, just as if it had been read from the database.
The entity to attach.
The entity.
Attach is used to repopulate a context with an entity that is known to already exist in the database.
SaveChanges will therefore not attempt to insert an attached entity into the database because
it is assumed to already be there.
Note that entities that are already in the context in some other state will have their state set
to Unchanged. Attach is a no-op if the entity is already in the context in the Unchanged state.
Adds the given entity to the context underlying the set in the Added state such that it will
be inserted into the database when SaveChanges is called.
The entity to add.
The entity.
Note that entities that are already in the context in some other state will have their state set
to Added. Add is a no-op if the entity is already in the context in the Added state.
Adds the given collection of entities into context underlying the set with each entity being put into
the Added state such that it will be inserted into the database when SaveChanges is called.
The collection of entities to add.
The collection of entities.
Note that if is set to true (which is
the default), then DetectChanges will be called once before adding any entities and will not be called
again. This means that in some situations AddRange may perform significantly better than calling
Add multiple times would do.
Note that entities that are already in the context in some other state will have their state set to
Added. AddRange is a no-op for entities that are already in the context in the Added state.
Marks the given entity as Deleted such that it will be deleted from the database when SaveChanges
is called. Note that the entity must exist in the context in some other state before this method
is called.
The entity to remove.
The entity.
Note that if the entity exists in the context in the Added state, then this method
will cause it to be detached from the context. This is because an Added entity is assumed not to
exist in the database such that trying to delete it does not make sense.
Removes the given collection of entities from the context underlying the set with each entity being put into
the Deleted state such that it will be deleted from the database when SaveChanges is called.
The collection of entities to delete.
The collection of entities.
Note that if is set to true (which is

Note that if any entity exists in the context in the Added state, then this method
will cause it to be detached from the context. This is because an Added entity is assumed not to
exist in the database such that trying to delete it does not make sense.
Creates a new instance of an entity for the type of this set.
Note that this instance is NOT added or attached to the set.
The instance returned will be a proxy if the underlying context is configured to create
proxies and the entity type meets the requirements for creating a proxy.

Returns the equivalent generic object.
The type of entity for which the set was created.
The generic set object.
Creates a raw SQL query that will return entities in this set. By default, the
entities returned are tracked by the context; this can be changed by calling
AsNoTracking on the returned.
Note that the entities returned are always of the type for this set and never of
a derived type. If the table or tables queried may contain data for other entity
types, then the SQL query must be written appropriately to ensure that only entities of
the correct type are returned.
As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter.
context.Set(typeof(Blog)).SqlQuery("SELECT * FROM dbo.Posts WHERE Author = @p0", userSuppliedAuthor);
Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string.
context.Set(typeof(Blog)).SqlQuery("SELECT * FROM dbo.Posts WHERE Author = @author", new SqlParameter("@author", userSuppliedAuthor));
The SQL query string.
The parameters to apply to the SQL query string. If output parameters are used, their values
will not be available until the results have been read completely. This is due to the underlying
behavior of DbDataReader, see http://go.microsoft.com/fwlink/?LinkID=398589 for more details.
A object that will execute the query when it is enumerated.
A DbSet represents the collection of all entities in the context, or that can be queried from the
database, of a given type. DbSet objects are created from a DbContext using the DbContext.Set method.
Note that DbSet does not support MEST (Multiple Entity Sets per Type) meaning that there is always a
one-to-one correlation between a type and a set.
The type that defines the set.
Creates an instance of a when called from the constructor of a derived
type that will be used as a test double for DbSets. Methods and properties that will be used by the
test double must be implemented by the test double except AsNoTracking, AsStreaming, an Include where
the default implementation is a no-op.

An implementation of this interface is used to initialize the underlying database when
an instance of a derived class is used for the first time.
This initialization can conditionally create the database and/or seed it with data.
The strategy used is set using the static InitializationStrategy property of the
class.
The following implementations are provided: ,

The type of the context.
Executes the strategy to initialize the database for the given context.
The context.
An represents the collection of all entities in the context, or that
can be queried from the database, of a given type. is a concrete
implementation of IDbSet.
was originally intended to allow creation of test doubles (mocks or
fakes) for . However, this approach has issues in that adding new members
to an interface breaks existing code that already implements the interface without the new members.
Therefore, starting with EF6, no new members will be added to this interface and it is recommended
that be used as the base class for test doubles.
The type that defines the set.
Finds an entity with the given primary key values.
If an entity with the given primary key values exists in the context, then it is
returned immediately without making a request to the store. Otherwise, a request
is made to the store for an entity with the given primary key values and this entity,
if found, is attached to the context and returned. If no entity is found in the
context or the store, then null is returned.

Inherit from this class to create a service that allows for code generation of custom annotations as part of
scaffolding Migrations. The derived class should be set onto the .
Note that an is not needed if the annotation uses a simple string value,
or if calling ToString on the annotation object is sufficient for use in the scaffolded Migration.

Types used as custom annotations can implement this interface to indicate that an attempt to use
multiple annotations with the same name on a given table or column may be possible by merging
the multiple annotations into one.
Normally there can only be one custom annotation with a given name on a given table or
column. If a table or column ends up with multiple annotations, for example, because
multiple CLR properties map to the same column, then an exception will be thrown.
However, if the annotation type implements this interface, then the two annotations will be
checked for compatibility using the method and, if compatible,
will be merged into one using the method.
Returns true if this annotation does not conflict with the given annotation such that
the two can be combined together using the method.

only expected to succeed if returns true.
The annotation to merge with this one.
A new merged annotation.
Instances of this class are used as custom annotations for representing database indexes in an
Entity Framework model.
An index annotation is added to a Code First model when an is placed on
a mapped property of that model. This is used by Entity Framework Migrations to create indexes on
mapped database columns. Note that multiple index attributes on a property will be merged into a
single annotation for the column. Similarly, index attributes on multiple properties that map to the
same column will be merged into a single annotation for the column. This means that one index
annotation can represent multiple indexes. Within an annotation there can be only one index with any
given name.
The name used when this annotation is stored in Entity Framework metadata or serialized into
an SSDL/EDMX file.
Creates a new annotation for the given index.
An index attributes representing an index.
Creates a new annotation for the given collection of indexes.
Index attributes representing one or more indexes.
Gets the indexes represented by this annotation.
Returns true if this annotation does not conflict with the given annotation such that
the two can be combined together using the method.
Each index annotation contains at most one with a given name.
Two annotations are considered compatible if each IndexAttribute with a given name is only
contained in one annotation or the other, or if both annotations contain an IndexAttribute
with the given name.
The annotation to compare.
A CompatibilityResult indicating whether or not this annotation is compatible with the other.
Merges this annotation with the given annotation and returns a new annotation containing the merged indexes.
Each index annotation contains at most one with a given name.
The merged annotation will contain IndexAttributes from both this and the other annotation.
If both annotations contain an IndexAttribute with the same name, then the merged annotation
will contain one IndexAttribute with that name.
The annotation to merge with this one.
A new annotation with indexes from both annotations merged.
The other annotation contains indexes that are not compatible with indexes in this annotation.
This class is used to serialize and deserialize objects so that they
can be stored in the EDMX form of the Entity Framework model.
An example of the serialized format is:

Call this method to add a instance to the Chain of
Responsibility of resolvers that are used to resolve dependencies needed by the Entity Framework.
Resolvers are asked to resolve dependencies in reverse order from which they are added. This means
that a resolver can be added to override resolution of a dependency that would already have been
resolved in a different way.

will always be used in preference to using a dependency resolver added here, unless the
overrideConfigFile is set to true in which case the resolver added here will also override config
file settings.

This convention causes DbModelBuilder to include metadata about the model
when it builds the model. When creates a model by convention it will
add this convention to the list of those used by the DbModelBuilder. This will then result in
model metadata being written to the database if the DbContext is used to create the database.
This can then be used as a quick check to see if the model has changed since the last time it was
used against the database.
This convention can be removed from the conventions by overriding
the OnModelCreating method on a derived DbContext class.

property. A different formatter can be used by creating a class that inherits from this class and overrides
some or all methods to change behavior.
To set the new formatter create a code-based configuration for EF using and then
set the formatter class to use with .
Note that setting the type of formatter to use with this method does change the way command are
logged when is used. It is still necessary to set a
onto before any commands will be logged.
For more low-level control over logging/interception see and
.
Interceptors can also be registered in the config file of the application.
See http://go.microsoft.com/fwlink/?LinkId=260883 for more information about Entity Framework configuration.

If execution of the operation completes without throwing, then this property will contain
the result of the operation. If the operation was suppressed or did not fail, then this property
will always contain the default value for the generic type.
When an operation completes without throwing both this property and the
property are set. However, the property can be set or changed by interceptors,
while this property will always represent the actual result returned by the operation, if any.
If this property is set before the operation has executed, then execution of the operation will
be suppressed and the set result will be returned instead. Otherwise, if the operation succeeds, then
this property will be set to the returned result. In either case, interceptors that run
after the operation can change this property to change the result that will be returned.
When an operation completes without throwing both this property and the
property are set. However, this property can be set or changed by interceptors, while the

When an operation fails both this property and the property are set
to the exception that was thrown. However, the property can be set or
changed by interceptors, while this property will always represent the original exception thrown.
If this property is set before the operation has executed, then execution of the operation will
be suppressed and the set exception will be thrown instead. Otherwise, if the operation fails, then
this property will be set to the exception that was thrown. In either case, interceptors that run

Note that the database may already contain seed data when this method runs. This means that
implementations of this method must check whether or not seed data is present and/or up-to-date
and then only make changes if necessary and in a non-destructive way. The
can be used to help with this, but for seeding large amounts of data it may be necessary to do less
granular checks if performance is an issue.

Specifies the related objects to include in the query results.
This extension method calls the Include(String) method of the source object,
if such a method exists. If the source does not have a matching method,
then this method does nothing. The , ,
and types all have an appropriate Include method to call.
Paths are all-inclusive. For example, if an include call indicates Include("Orders.OrderLines"), not only will
OrderLines be included, but also Orders. When you call the Include method, the query path is only valid on
the returned instance of the . Other instances of

To include a single reference: query.Include(e => e.Level1Reference)
To include a single collection: query.Include(e => e.Level1Collection)
To include a reference and then a reference one level down: query.Include(e => e.Level1Reference.Level2Reference)
To include a reference and then a collection one level down: query.Include(e => e.Level1Reference.Level2Collection)
To include a collection and then a reference one level down: query.Include(e => e.Level1Collection.Select(l1 => l1.Level2Reference))

When this attribute is placed on a property it indicates that the database column to which the
property is mapped has an index.
This attribute is used by Entity Framework Migrations to create indexes on mapped database columns.
Multi-column indexes are created by using the same index name in multiple attributes. The information
in these attributes is then merged together to specify the actual database index.
Creates a instance for an index that will be named by convention and
has no column order, clustering, or uniqueness specified.
Creates a instance for an index with the given name and
has no column order, clustering, or uniqueness specified.
The index name.
Creates a instance for an index with the given name and column order,
but with no clustering or uniqueness specified.
Multi-column indexes are created by using the same index name in multiple attributes. The information
in these attributes is then merged together to specify the actual database index.
The index name.
A number which will be used to determine column ordering for multi-column indexes.
The index name.
Multi-column indexes are created by using the same index name in multiple attributes. The information
in these attributes is then merged together to specify the actual database index.
A number which will be used to determine column ordering for multi-column indexes. This will be -1 if no
column order has been specified.
Multi-column indexes are created by using the same index name in multiple attributes. The information
in these attributes is then merged together to specify the actual database index.
Set this property to true to define a clustered index. Set this property to false to define a
non-clustered index.
The value of this property is only relevant if returns true.
If returns false, then the value of this property is meaningless.
Returns true if has been set to a value.
Set this property to true to define a unique index. Set this property to false to define a
non-unique index.
The value of this property is only relevant if returns true.
If returns false, then the value of this property is meaningless.
Returns true if has been set to a value.
Returns a different ID for each object instance such that type descriptors won't
attempt to combine all IndexAttribute instances into a single instance.
Returns true if this attribute specifies the same name and configuration as the given attribute.
The attribute to compare.
True if the other object is equal to this object; otherwise false.
Returns true if this attribute specifies the same name and configuration as the given attribute.
