Visual Studio - Designer process terminated unexpectedly

Question

After opening project (new or old) Visual Studio shows warning \"Designer terminated unexpectedly\" (can see in the picture below). What could cause this error? And

Answer 1

Start Visual Studio As Administrator~!

I had the same problem when i started working in Team Projects, so almost everything did not work including the designer, properties menu, debugging and so on.. (which is totally unusual for anything to cause all these problems except for Administrator Privileges issues probably in most cases).

Don't know why or what caused it, but at least it works.
