DbContext ObjectContext

from:  http://msdn.microsoft.com/en-us/library/system.data.entity.dbcontext(v=vs.103).aspx

DbContext wraps ObjectContext and exposes the most commonly used features of ObjectContext by using simplified and more intuitive APIs. You can access the underlyingObjectContext whenever you need to use features that are not supported by DbContext. For more information, see What’s Not Supported.
