Reporting an issue I've ran into on the Roslyn based fork of this Repository here created by @vojtechkacmarik.
When creating a new 'Blazor' app then trying to open the Startup.cs file I get a 'NullReferenceException', possibly due to the way the Extension calculates Constructor complexity and hits an issue where a Constructor uses Expression Body syntax.

[Error Log]
