Error 1 The type or namespace name 'Advisors' could not be found (are you missing a using directive or an assembly reference?) F:\Trinity_new\Trinity\Forms\MainForm.cs 63 37 Trinity

Advisors is a maintenance form in my solution and I can see it in the solution explorer.

How do I resolve this error?

Not sure this is your problem, and you might already know what I am goind to say, but just in case you don't... your application database connection has nothing to do with BO Mapper and such. These are all located through the StrataFrame Database connection.

So, you might want to check that. Go to the StrataFrame menu on the Visual Studio IDE, choose Database Connection. The StrataFrame Data Store should be selected. You can edit it and make shure that this connection is pointing to the StrataFrame Database, not anyone else.

Hope it helps.
