Since installing VS 2013 and Update 4 I've tried opening a XAML file.
I get the waiting for an operation to complete box forever (like 20 min) then it kills it and reloads the solution. While its going on my cpu is pegged at 50%
Anyone else experienced this?
This is blocking me from working .. I have to keep going back to VS 2012 to get it to load.
Try resetting Visual Studio's settings through the Visual Studio command prompt with the following command:
Its recommended you export your existing IDE settings via the Tools | Import/Export Settings option before running the above though so you'll at least retain your key bindings (if you customize them).
Hope this helps.
