I just upgraded from Visual Studio 2013 to 2015 and now I am having trouble with breakpoints.
It's a hit or a miss where break points will actually work and if I set one while debugging I get the error:
The breakpoint failed to bind.
Any help would be appreciated. I am about ready to give up on 2015 and go back.
I had the same problem but a different solution. Please note I updated to VS 2015 Update 1 and the problem is still there.
In previous edition of VS starting debug automatically triggered a build in debug mode. But with VS2015 it does not.
So if your last build was in release mode, and you try debugging, breakpoint won't work.
You have to manually build in debug mode first, then start debugging.
I had the same problem.
I solved it disabling "Optimize code" option in project properties Build tab.
This may seem trivial, but after a lot of headscratching with the same issues as you mention, I found out that my build was set to "release" instead of "debug" when I tried debugging.. re-building the solution for "debug" fixed it, and I could set breakpoints as normal
