Package Load Failure Microsoft.VisualStudio.Xaml

Few days ago all of the sudden VisualSudio 2008 popped out this error message "Package Load Failure Microsoft.VisualStudio.Xaml blah blah yes/no" I didn't pay much attention to it (because it was yes/no message box and in that case i always click yes :)) After that Visual Studio didn't load 2 of 5 C# projects in my solution complaining that project type is not supported by current installation. Of course i was baffled because I din't connect error message to this problem right away. Apparently by clicking Yes I've disabled Visual Studio package (because it failed to load obviously). OK, no problem devenv /reset will fix this right? Wrong! Visual Studio tries to load Microsoft.VisualStudio.Xaml but fails for no apparent reason. I've googled up bunch of "fixes" for this problem but none of devenv switches or even Visual Studio Repair works. So this is what worked for me:

Uninstall Visual Studio
Install Visual Studio
Apply Visual Studio SP1

I hope this helps.

I have the same problem, but I was too lazy to reinstall VS, only .Net framework, an of course it didn't worked. So thanks, I'll try your method;)
