NullReferenceException on any sample

description

After facing the add-in trouble (both the initial loading and the auto restart) I get the following error on any sample:
 
System.NullReferenceException: Object reference not set to an instance of an object.
at System.Windows.Forms.Control.get_Controls()
at VSLab.Viewlet..ctor()
at VSLab.Chart.GraphControl..ctor()
at <StartupCode$FSI_0006>.$FSI_0006._main()
stopped due to error
 
It appears to occur when creating an object like 'let gv = new GraphControl()' and 'let monitor = new VSMon()'.
 
I'd love to see this work.

I installed the November 2008 DirectX SDK in order to get the Managed Direct-X libraries. What version of the Managed Direct-X libraries are required in order to use the 3D function viewer? Are the ones that come with that SDK version compatible?
