Missing designer support for XAML and WPF in Visual Studio

Today I came across the following error opening a WPF XAML file in Visual Studio:

There is no editor available for 'xxx'. Make sure the application for the file type (.xaml) is installed

You could get the same kind of error for aspx:

There is no editor available for 'xxx'. Make sure the application for the file type (.asxp) is installed

I tried upgrading to Service Pack 1 of Visual Studio, but it didn't help at all! For some strange reason there seems to be some VSPacakges that suddenly got a SkipLoading tag. You can easily solve this through the Visual Studio command prompt by typing:

devenv /resetskippkgs

This clears all SkipLoading tags added to VSPackages, normally added by users wanting to avoid loading problem VSPackages.
