That's just coding style, which by itself is not a new dialect. Yes a bunch of APIs in Unity use different naming conventions from the rest of .NET world, but the language is the same.

The new HPC#/Burst indeed are subsets of C#, but that's a very recent development, and completely unrelated to "Unity had to make their own C# dialect to avoid Novell/Xamarin licensing issues".

I have worked at Unity since 2006. Yes Unity was Mac only at that point, but it still used Mono there.

My remark had to do more with being stuck in a v3.5 world, thus making Unity devs live in an universe quite different than what everyone else is using in terms of APIs and language features, on top of Unity specific behaviors like those magical methods called by the component framework.
