VS2010 – missing designer.cs files

I was going to debug some code for a customer. I converted the application from .NET 1.1 to .NET 2.0, and suddenly I discovered that the designer files where missing for most of the aspx web pages. I remembered this problem for earlier, but couldn’t figure out the solution myself, and had to ask a developers best friend “google” 🙂

I found  a nice post by Jan Schreuder describing this problem and a solution.
