Hello,
I was using Visual Studio 2015 with Inventor 2016 ETO Series Studio for a longer time and everything was fine for me.
Yesterday, CompletionController started to generate "Object reference not set to an instance" error when I try to edit .iks document, when selecting some Intent keyword from list.
The same problem exists on 2 machines.
Is there a way to fix it?
description in VS ActivityLog.xml is:
System.NullReferenceException: Object reference not set to an instance of an object.
