Why the MS C# compiler was NOT written in C#?

Assuming Microsoft's C# compiler was the first C# compiler to exist,
what compiler would they have used to compile a C# version of the C#
compiler?

Reminds me of an interview I once read with Bjarne Stroustrup where he
mentioned he wrote the first C++ compiler in C++. He added a bunch of
macros in C to take C++ code and transform it to C. He then wrote the
compiler in C++, used the macros to turn it to C, compiled it and then used
the resulting compiler to compile the C++.
