Contrary to Python, .NET can do plenty on its JIT and AOT compilers, and low level features used to support C++/CLI on the runtime.

All tested libraries here are pure C#. You simply do not need "native" components* for tasks like these in C#, since JIT/ILC is more than capable at producing performant "native" code.

* for all intents and purposes that's what C# compiles to under NAOT. Even with JIT there is no interpreter stage, CIL is always compiled to native code.
