Answer 1

In my case, there was a new web.config file created after I use Profiler. Restoring web.config to the previous version, resolved this issue. It was a VS2015 C# web application.

VS breakpoints cannot bind on async methods.

I had an App Dynamics agent installed that caused this. Remove that and you are good to go.

Answer 3

While this is a much later build (VS2017) I had this issue with C# projects. Tried cleaning, rebuilding, restarting visual studio, etc.

What fixed it was closing Visual Studio and deleting the .vs folder, which is a hidden folder located in the solution directory. Deleting the .vs folder should not cause you any problems, although you will need to reset your startup project.

Answer 4

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

Answer 5

I didn't change the 'optimize' setting, but based on other answers here, I

1. Set Solution Explorer to Show All Files for the project
2. Deleted the hidden bin and debug folders
3. Performed a 'Clean' on the project
4. Performed 'Rebuild' on the project

So far this has fixed it for me. Seems like updating to VS2015 Update 2 has borked a few things on my system.

In case you are publishing your web-application check that Configuration is set to Debug(by default in debug configuration is set such that code not is optimized and symbol table is fully created).
