Instances of this class are used to create DbConnection objects for SQL Server LocalDb based on a given database name or connection string.

An instance of this class can be set on the class or in the app.config/web.config for the application to cause all DbContexts created with no connection information or just a database name to use SQL Server LocalDb by default. This class is immutable since multiple threads may access instances simultaneously when creating connections.

Implementations of this interface are used to create DbConnection objects for a type of database server based on a given database name. An Instance is set on the class to cause all DbContexts created with no connection information or just a database name or connection string to use a certain type of database server by default. Two implementations of this interface are provided: is used to create connections to Microsoft SQL Server, including EXPRESS editions. is used to create connections to Microsoft SQL Server Compact Editions. Other implementations for other database servers can be added as needed. Note that implementations should be thread safe or immutable since they may be accessed by multiple threads at the same time.

Handles creating databases either using the core provider or the Migrations pipeline.

Creates a database using the core provider (i.e. ObjectContext.CreateDatabase) or by using Code First Migrations to create an empty database and the perform an automatic migration to the current model. Migrations is used if Code First is being used and the EF provider is for SQL Server or SQL Compact. The core is used for non-Code First models and for other providers even when using Code First.

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 .\SQLEXPRESS on the local machine 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.

Initializes the internal context, discovers and initializes sets, and initializes from a model if one is provided.

Discovers DbSets and initializes them.

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 ModelBuidler, 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.

Used for generating values that are always in sequential order for the calling thread.

Returns the value of unless this value would be the same as the last value returned by this thread calling this method, in which case the thread pushes the value a little bit into the future. The comparison is in terms of the form used to store migration ID in the database--i.e. to the 1/10 second.

There should never be any pushing to the future involved for normal use of migrations, but when this method is called in rapid succession while testing or otherwise calling the DbMigrator APIs there may be occasional sleeping.

Same as UtcNow method bur returns the time in the timestamp format used in migration IDs.

An implementation of IDatabaseInitializer that will recreate and optionally re-seed the database only if the database does not exist. To seed the database, create a derived class and override the Seed method.

The type of the context.

Executes the strategy to initialize the database for the given context.

The context.

A that should be overridden to actually add data to the context for seeding. The default implementation does nothing.

The context to seed.

An instances 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.

Creates a Database backed by the given context. This object can be used to create a database, check for database existence, and delete a database.

The context that defines the database connection and model.

Gets or sets the database initialization strategy. The database initialization strategy is called when instance is initialized from a . The strategy can optionally check for database existence, create a new database, and seed the database with data. The default strategy is an instance of .

The type of the context. The strategy. The database creation strategy.

Internal version of SetInitializer that allows the strategy to be locked such that it cannot be replaced by another call to SetInitializer. This allows strategies set in the app.config to win over strategies set in code.

The type of the context. The strategy. if set to true then the strategy is locked.

Runs the 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 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. 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 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.

Resets the DefaultConnectionFactory to its initial value. Currently, this method is only used by test code.

Performs the operation defined by the given delegate using the given lazy connection, ensuring that the lazy connection is disposed after use.

Information used to create a DbConnection. The operation to perform. The return value of the operation.

Performs the operation defined by the given delegate against a connection. The connection is either the connection accessed from the context backing this object, or is obtained from the connection information passed to one of the static methods.

The connection to use. The operation to perform. The return value of the operation.

Returns an empty ObjectContext that can be used to perform delete/exists operations.

The connection for which to create an ObjectContext The empty context.

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 . 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.

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 know 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 4.1 through 4.3 should be used.

Indicates that the version of the and conventions shipped with Entity Framework 5.0 when targeting .NET 4 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 know 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.

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.

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.

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.

A factory for creating derived instances. Implement this interface to enable design-time services for context types that do not have a public default constructor. At design-time, derived instances can be created in order to enable specific design-time experiences such as model rendering, DDL generation etc. To enable design-time instantiation for derived types that do not have a public, default constructor, implement this interface. Design-time services will auto-discover implementations of this interface that are in the same assembly as the derived type.

Creates a new instance of a derived type.

An instance of TContext

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.

Instances of this class are used to create DbConnection objects for SQL Server Compact Edition based on a given database name or connection string.

It is necessary to provide the provider invariant name of the SQL Server Compact Edition to use when creating an instance of this class. This is because different versions of SQL Server Compact Editions use different invariant names. An instance of this class can be set on the class to cause all DbContexts created with no connection information or just a database name or connection string to use SQL Server Compact Edition by default. This class is immutable since multiple threads may access instances simultaneously when creating connections.

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.

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.
