I have a problem with debugging my program in Visual Studio 2012 - when I try to debug the code by inserting some breakpoints, they seem not to work - when I hover on them a message pops up
The breakpoint will not currently be hit. Unexpected symbol reader error while processing <file.exe>
I tried searching for similar problems in the internet but I haven't found any solutions I'd appreciate any help, thanks!
For Visual Studio 2017, closing all open instances and restarting worked for me. I may have gotten away with closing fewer, for example instances with unrelated solutions open, but I have not tested that.
[VS 2012] Ok I got the answer that fixed this problem, so I'll post this here so that people have no such problem in the future.
A solution is to change
from Auto to Mixed. The breakpoints will automatically work.
[VS 2015] Closing all instances of VS 2015 and restarting fixes the problem for a while at least. The 2012 fix does not work.
I had a VS 2017 C++ DLL called from VS 2013 C# application. Upgrading the application to VS 2017 solved the problem.
