Visual Studio 2010: compiler error designer.cs

Question

I use Visual Studio 2010, if I use the update panels and make some changes in Markups, then in designer.cs System.UI is converted to System.Web.Webparts, which forces me to change all the files "designer.cs".

Has anyone else experienced this and are there any solutions?

This seems to be a VS2010 bug in some versions. Now they believe that this is fixed. Check this will probably help: VS10-KB981167-x86.exe
