I've got 2 projects working on .Net Core, and one about to go live next week. The tooling in VS2017 makes it even better. My only real problems have been using the new libraries (EFCore, aspnet core) and finding compatible libs. Documentation is a bit of a pain due to all the earlier changes that are fossilized in blog posts. Other than that, it's been pretty smooth. Dev and test on VS/Win, deploy to Linux. Though I've also done the same with Mono and it's been pretty good. Mono starts a lot faster - I don't get why "dotnet X" takes 5 seconds no matter what X is. Fwiw I'm excited about Rust and use that too, and even have a few in-the-wild users of my Rust open source stuff. So I think the line about excited about vs actually use is nonsense used to justify shitty design decisions ala C++ or Go.
