Description
VSF_TYPE_MARKDOWNDebugging WPF applications is exceptionally slow. When the debugged application causes a UI refresh (not sure what is triggering it, maybe applying templates), it does it very slowly. During this time you can see the output window filling up with warnings like
"System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='..."
though also very slowly (~1 per second).
Debugging the same application works fine with VS 2017.
