VS2012 - XDesProc hangs when Xaml file is opened

Question

In VS2012 whenever I try to open a xaml file (even in full XAML view) the XDesProc process keeps spinning and hangs visual studio. I tried killing it but it respawns.

With my Visual Studio 2012.4, and 2gb of RAM used by XDeskProc, I resolve the problem by turning off the data loading in View Model’s constructor if in design mode. Loading the ItemsSources of my many Comboboxes just bogged down the designer

If DesignerProperties.GetIsInDesignMode(New DependencyObject) Then ‘ Do nothing Else ‘ Do something End If
