VS Crashes when right clicking on designer surface

Hi @KlausLoeffelmann

I'm trying to implement simple context menus, but any right click causes the following error:

System.InvalidOperationException
HResult=0x80131509
Message=The service 'Microsoft.DotNet.DesignTools.Client.Designers.IEventHandlerService' must be installed for this feature to work. Ensure that this service is available.
Source=Microsoft.WinForms.Utilities.Shared
StackTrace:

IEventHandlerService is internal, so I'm not sure how to "install" it.

Please assist in how to resolve this error and open a simple context menu when right clicking on designer surface

Regards
Tim
