Answer 1

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.

Answer 3

The new Update for Microsoft Visual Studio 2015 Update 3 (KB3165756) has fixed the breakpoint issue for me where I'm trying to inspect the local variables in C# code embedded in cshtml files in ASP.NET Core applications.

Answer 4

the solution is to disable the design optimization.

Project Properties> Build> Advanced Compile Options> Enable Optimizations

Answer 5

I know this is an old post but in case all the other tricks above don't work for you make sure the image you are trying to debug is current. For some reason after publishing and transferring a .NET Core project to my Raspberry Pi 'unzip' on the RPi was not copying and overwriting some DLLs in the working directory. When I attached the debugger thinking everything was OK some breakpoints were getting hit, others were not and some others were giving me the "can't bind" error. Once I resolved the unzip issue all my breakpoints and symbols came back. I hope this helps.

I tried everything suggested here. Eventually, I set the "Specific Page" in Project Properties -> Web to my local start URL, page and query parameter. Did a clean and rebuild in debug mode and it hit my breakpoint.
