Actually, not a bug. I had the settings for a 'Statement' and this needs to be compiled as part of a file.

It is actually still a bug. A NullReferenceException is always a bug, no matter what.

This one is in Roslyn though: https://github.com/dotnet/roslyn/issues/17458

Once they fix that you should be able to generate statement level for this code as well.
