Compatible .NET csc and Mono mcs

Question

I know that .NET and Mono are binary compatible, but given the source code, do csc and mcs produce an exact 100% identical binary CLI executable? Is it possible to determine if the executable is compiled using csc or mcs?

Answer 1

Many things are not fully defined in the specification or are implementation-specific extensions.

Examples of incomplete ones:

• ; ecma; MS, # 4.0, , IIRC
• Expression ( ); " " ( )

:

• P/Invoke
• COM (.. new )

, : IL, csc [g] mcs, csc.
