The connection factory to use when creating a DbConnection from just a database name or a connection string.
Assembly: EntityFramework (in EntityFramework.dll)
This is used when just a database name or connection string is given to DbContext 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.
