A change that (again) makes VS 2015 the default compiler on Windows just landed. The CL is:
All known issues have been addressed by using a pre-release version of Update 2 that fixes some code-gen bugs and linker instability. The code-gen bugs should not hit non-PGO builds, and the linker instability is rare, so those using Update 1 of VS 2015 should be fine for now. Using VS 2015 RTM is not supported - it has too many bugs.
Any questions? Ask me. But I'll be AFK for 6-7 hours - it's late here - but will check in at PST morning.
If you want to continue using VS 2013 you can temporarily do this with:
This won't work long-term, because eventually we will check in code that requires VS 2015. However we should try to avoid doing that initially, in case we have to revert for some reason.
