Answer 5

I get this visual studio bug too now and then, and I deeply ignore the error text, instead I do the following:

1. Close the Design-tab
2. Reopens the Design mode by double click in Solution Explorer, or by right clicking Source code tab and select View Designer

Maybe this can help you out.
