Description
After migrating my project to the latest version of MSAGL, I am getting the following error in Visual Studio 2017 when loading a WinForm containing a Microsoft.Msagl.GraphViewerGdi.GViewer control:
Method 'InvalidateBeforeTheChange' in type 'Microsoft.Msagl.GraphViewerGdi.GViewer' from assembly 'Microsoft.Msagl.GraphViewerGdi, Version=3.0.0.0, Culture=neutral, PublicKeyToken=fffc27ea4058b3a1' does not have an implementation.
The control works fine as runtime though.

Research direction
Reproduce the design-time load failure in Visual Studio 2017 with a WinForm containing Microsoft.Msagl.GraphViewerGdi.GViewer after migrating to the latest MSAGL version. Start by inspecting GViewer and the Microsoft.Msagl.GraphViewerGdi assembly around InvalidateBeforeTheChange; done means the control loads in the designer without the missing-implementation error while retaining its working runtime behavior.
