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 created with useSeedData set to true.

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.

This method returns true if the context has a model hash and the database contains a model hash and these hashes match. This indicates that the model used to create the database is the same as the current model and so the two can be used together.

If set to true then an exception will be thrown if no model metadata is found either in the model associated with the context or in the database itself. 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.

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. The default connection factory creates a connection to SQL Express on the local machine. However, this default may be changed by an application framework.

An implementation of IDatabaseInitializer that will DELETE, recreate, and optionally re-seed the database only if the model has changed since the database was created. This is achieved by writing a hash of the store model to the database when it is created and then comparing that hash with one generated from the current model. To seed the database, create a derived class and override the Seed method.

The context to seed.

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.

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.

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.

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.

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.

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.

Validates entities or complex types implementing IValidatableObject interface.

Display attribute used to specify the display name for an entity or complex property.

Validates an entity or a complex type implementing IValidatableObject interface. This method is virtual to allow mocking.

Validation context. Never null. Property to validate. Null if this is the entity that will be validated. Never null if this is the complex type that will be validated. Validation error as . Empty if no errors. Never null. Note that is used to figure out what needs to be validated. If it not null the complex type will be validated otherwise the entity will be validated. Also if this is an IValidatableObject complex type but the instance (.CurrentValue) is null we won't validate anything and will not return any errors. The reason for this is that Validation is supposed to validate using information the user provided and not some additional implicit rules. (ObjectContext will throw for operations that involve null complex properties).

Validates a property, complex property or an entity using validation attributes the property or the complex/entity type is decorated with.

Note that this class is used for validating primitive properties using attributes declared on the property (property level validation) and complex properties and entities using attributes declared on the type (type level validation).
