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?

Humm, that is really extrange.

1. Does this happen after doing what I suggested in the previous post?
2. Have you install any new program, Windows Update or something else to your computer?

A couple of days ago, I had a situation where I could not generate any BO from the BOM and it turned out to be that the .NET 2.0 runtime framework was corrupted, I reinstall it and that fix my problem.  This could be related somehow.
