What did they write C♯ in, though?
 

 
First release was written in assembly code. Subsequent releases are in
C# itself. The c# language is class based object oriented, so you don't
need anything else to expand the language. Just write a new object and
compile it to be used by other objects. This is the same as in C or C++.
First release were in assembly and any enhancement were in the same
language = C or C++ respectively.

Do you have insider info?  Writing substantial piece of code in
nineties using assembler would be highly unusual.  Slightly
earlier Microsoft supposedly had a rule that all code should
be in C (presumably with exceptions for lowest level machine
dependencies and some performance critical parts, but both
should be relatively small).

Also, when a company has compilers for multiple languages, it
is natural to share substantial part for other languages.  In
case of gcc Ada front-end is in Ada, but most work is in "middle
end" that is common to all compilers in gcc and is written in C++.
I would guess that now Microsoft C compiler is written in C++.
