How to set the color of matching braces in VS 2015?
I just tried it with the RC release we shipped this week and also seeing the problem. Will follow up with the team and get this fixed. I'll post updates here. Thanks for sharing the problem!
Update: I confirmed with the team that this is a known issue and is on the list to get fixed.
Tools → Options → Environment → Font and Colors → Punctuations
Affects all parentheses, commas etc.
On dark view it defaults to black over black
ReSharper also applies color to matching braces. You can turn this off in ReSharper options and then your VS color setting should be applied.
