I'm using the Entity Data Model Wizard in Visual Studio Express 2013 to create an EDM on an SQL 2012 Enterprise database that was already created.
Went through all the steps (working with Ying Bai's "Practical Database Programming with Visual Basic.NET" book) but when I click "Test Connection," I get this message:
“The attempt to attach to the database failed with the following information:
The user instance login flag is not supported on this version of SQL Server.
The connection will be closed.”
Any help in solving this would be appreciated.
Thanks,
Philip
