     <!-- ==== Referencing Analyzers ====
       Normally you never actually reference the analyzer they just get used by the compiler internally.
       When adding a NuGet reference it just does that behind the scenes. For these unit tests I needed
       to reference the type, so that is this weird workaround of using the path and navigating to the dll
