IVSMDDesigner.Dispose Method ()
Releases all resources used by the IVSMDDesigner.
Assembly: Microsoft.VisualStudio.Designer.Interfaces (in Microsoft.VisualStudio.Designer.Interfaces.dll)
This should be called before the designer is destroyed. If you are using the view returned from GetView, closing the window pane within the view will also call Dispose(), so you would not have to call Dispose() on the designer.
