VS/MSVC has improved a lot. There are details here: https://blogs.msdn.microsoft.com/vcblog/2016/06/07/compiler-... but the long and short of it is that we are working on achieving complete C++98/11/14 compliance by (hopefully) the end of this year. And we have a number of C++ draft standard features implemented already, in both the compiler and the libraries.

Additionally, we're shipping a number of versions of Clang in VS (targeting Windows, targeting Linux/IOT, targeting Android/iOS) and contributing to the community. We're looking seriously into CMake support and contributing back to the community. And the VS Code editor runs on Unix-based OS with IntelliSense, debugging, etc.

So yes, VS has improved a lot, but we still have work to do.

I'd love to chat with you if you have questions. My email is firstname.lastname@microsoft.com. My full name is on the blog that I linked to but I'm really not that hard to find online.

And I've got questions for you if you use Clang and have any interest in Windows. Send me mail and we can maybe set up time for a phone/Skype call.
