1. Open attached solution (a solution containing a project that references a 
project in the same solution) 
2. In SomeMethod there is a l.Count() extension method call 
3. Just place your caret on the "Count". This will case an

The extension should display "Add Namespace Reference" for an extension method

I have managed to debug this issue and come up with a fix.

In method CR_ExtensionMethodsHelper.PlugIn1.GetProjectSymbols() there is an 
if-statement as follow:

if (reference == null)
  continue;

It should be:

if (reference == null || reference.AssemblyModel == null)
  continue;

This should now be fixed.

Please download v1.1 from this plugin's new home on github @ 

https://github.com/RoryBecker/CR_ExtensionMethodsHelper/releases/latest

Note: I suggest removing your existing plugin dll before attempting to use this 
new version, which does not install in the same location.
