I am getting the following build error in Visual Studio 2012 while trying to build a SQL database. This is a SQL Server 2012 database that I created with the Server Explorer, and imported to a SQL solution in Visual Studio. What do I need to do to correct this error? I haven't found an answer in help, or MSDN.
