Debugging doesn't start [closed]

Question

When I hit F5 (debugging mode) nothing happens. Building works correctly, exe file I can launch properly, but can't start debug. Why?

Answer 1

I have found a solution:

1. Close your Visual studio solution
2. Open your .csproj project header with notepad ++ for example.
3. Search for Tag in the section
4. Remove Config Tag completly
5. Open your solution and for me now debug works on my project

Answer 2

What worked for me was completely deleting the solution folder (had to reboot Windows to be allowed to do this), and then getting it back from source control. Sounds drastic - but it doesn't actually take very long.

Answer 3

My experience with Visual Studio 2015, I tried deleting all processes and restarting it didn't work. I tried deleting the bin directory, it didn't work.

Sadly, the only thing that worked was closing down and restarting Visual Studio 2015 in Admin mode. Sigh...

Answer 4

Same error, tried executing VS as Administrator and it worked.

Answer 5

Using Visual Studio 2017. Had dozen projects in a solution. Pressing debug would build with no error then do nothing.
Issue was one Project built to .Net 4.6 while the rest where .Net 4.0

Answer 6

I had this problem in a WPF application I was working on. When running the debugger, a process named MyApp.VsHost.exe would start and continue running in the background, but there would be no exceptions thrown and nothing in the Output window except build information.

It was because I had changed the namespace of my App class but did not update the Class attribute in App.xaml to match the new namespace. I changed the namespace in the xaml file and it worked again.
