NonComVisibleBaseClass was detected

Issue occured:

"A QueryInterface call was made requesting the default IDispatch interface of COM visible managed class 'xxx. However since this class does not have an explicit default interface and derives from non COM visible class 'System.Windows.Controls.UserControl', the QueryInterface call will fail. This is done to prevent the non COM visible base class from being constrained by the COM versioning rules.." 

How to Fix:

 Tools->Customize->Commands->select Debug->Click Add command->Select Debug->on right hand pane Exceptions click OK
