I have the problem when I create blank wpf .Net 3.5 project. Visual studio has throw an error and stop working. This is very strange because when I created other project in .Net 3.5 like windows form, it worked (aslo I have tested in other .Net framework without error).
Here is the copied error detail:

Also I tried repairing, uninstalling and reinstalling Visual Studio but it still has error.
Any help?
Update: error is only occurring when I open xaml file.
Finnaly, I have fixed it. When I tried to update VS SP1, I received the error
Then I recognize the %temp% directory doesn’t access. Then I go to environment variables and change %temp% path (I never touch this variable before), and the setup VS SP1 worked well. Also, this WPF error is fixed.
