I'm not sure if you're meaning something else, but is /M or /MP not the direction for you? Though C# compiles can be pretty long, my experience is it's usually File I/O and ancillary tasks that take up the majority of the time spent building. Even our primary product which is an absolutely enormous webapp with tons of projects takes only 11 minutes to fully compile and about 5 of that is just shuffling files around.

To take from another conversation, msbuild is very powerful but it's not very usable at all. So much tribal knowledge and secret handshakes you can't learn unless you have a contact in devdiv.

Beyond that, I've opened 3 incidents with Microsoft in the past and they've been nothing short of amazing. One guy even busted out an assembler and stepped through my code to identify that our issue was actually a deliberately closed accidental exploitation path. Enormously frustrating at the time, but he even provided a workaround for us but, like you say, it took several months.

To be specifically productive though: I feel like Roselyn does provide lots of value to developers in terms of what VS plugins can do. There are infinity re-implementations of the MS Compiler out there in terms of plugins and analysis tools. Would be nice to have everyone at least speaking the same language. I think the other thing this initiative does is put the license out there with permissiveness and clarity. Mono can feel comfortable lifting the concepts and integrating it in to their own without worrying about being sued now. This is all great things that they are making available their compiler as a tool and non-platform limited licensing. But - it's only a step it's not the end-game.

What are things you think really improve developers' lives that microsoft used to build they don't build now?
