Unmanaged code is native code. You can not produce that with
Microsofts C# compiler. C# code does not become unmanaged just
by using unsafe features.

C# managed code can somewhat work with unmanaged data though
interop classes.

That's "unsafe" code. "Unmanaged" code means code that's not produced from
..NET IL.
