Can you add a unit test that shows the fix (e.g. that would throw the NullReferenceException without your change to the source files but passes with them)? Having a test will prevent any regressions in the future.

Thanks!

I've verified by running make test-sdk SDK_FOLDER=csharp that without the change the test fails. :)
