.net - Errors in Windows Forms controls in designer view

Question

On occasion, I get the following error in design mode of some user controls in Visual Studio 2008:

The file 'UserControl.vb' does not support code parsing or generation because it is not contained within a project that supports code.

It doesn't happen on a consistent basis, but it happens enough to be annoying. Are there any common causes of this error?

And yes, it is in a project that supports code - last I checked, WinForms projects typically have code in them!

Answer 1

It is a bug in VS. It happens in VS2005 as well.

Don't waste your time: close VS, open it again and everything should work fine.
