I am new to working with the datacontext menu when setting up a new C#. 2010 application. Right now I am getting the following error message:"Error 2 'RpcSupport.Attestations' does not contain a definition for 'Receive_Date' and no extension method 'Receive_Date' accepting a first argument of type 'Rp.Att' could be found (are you missing a using directive or an assembly reference?) C:\RP\Attes.aspx.cs 94 16 RpSup.
Using the designer,I a att.dbml. However the designer fdoes not have the column 'Receive_Date' in the extension methods. Can you tell me what to try next or how to fix the problem?
