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.
