Remarks

Normally a subclass of DbConfiguration should be placed in the same assembly as the subclass of DbContext 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.
