Updating or inserting entities using Entity Framework indian14321-Aug-12 6:07 indian143 21-Aug-12 6:07  Hi All, I have an Asp.Net application in which I am trying to insert/upate a database table in the backend. But I am getting following message. Unable to update the EntitySet 'message' because it has a DefiningQuery and no <insertfunction> element exists in the <modificationfunctionmapping> element to support the current operation. Can anybody help me please by giving any suggestions, links or code snippet. Mean time I will be googling about the exception. Thanks in advance.
