AddCopyrightHeaderProvider raises NullReferenceException in VB

created 7 years ago

Sometimes I need to delete a form or a class from my VB.Net project. Often the first thing I will do is bring up the code, select all, and then comment it all out so I can determine that it is not being called somewhere (with my code you never know because of late-binding.) When I do this I receive an information bar in Visual Studio 2017 that says '"AddCopyrightHeaderProvider' encountered an error and has been disabled. Show Stack Trace [Enable] [Enable and Ignore future errors]" What is this?

The stack trace is:

System.NullReferenceException : Object reference not set to an instance of an object.
