[Mono-dev] Mono C# compiler switch

I would like to have an option to allow Mono to build with MCS, as it is currently faster.

Also, we were discussing internally in our Slack that it makes sense to update our C# compiler to include support for the new language features, as the new batch of language changes are relatively simple.

Subject: [Mono-dev] Mono C# compiler switch


Mono master has switched to Roslyn compiler as the default C# compiler. We'll keep both compilers (mcs and csc) available for some time but csc will be our preferred compiler from now on.

Our compiler always tracked Microsoft C# implementation very closely so I don't expect any upgrade issues, especially when both mcs and csc will co-exist because they have different set of supported command line arguments. For those using xbuild (or CodeDOM driven APIs) the upgrade should be automatic and only noticeable change will be different debug symbols format.
