My Visual Studio 2015 C# project has Web forms and classes defined under the App_Code folder. When building / rebuilding my solution, some specific classes under this folder never recompile - after compilation, their code is not changed (though seemingly they passed the compilation).

This shows up as run-time error messages for code I have just changed, not able to place breakpoints, etc.

I've attempted:

  • Rebuild

  • Clearing the ASP.NET temp folders

  • (There's no "Clean solution" because this is web forms)
  • Running as admin

The only solution that works: Reopening Visual Studio.

EDIT:

I have now also found that deleting the folder C:\Users\kobydo\AppData\Local\Temp\Temporary ASP.NET Files and then running a build also fixes this issue. But this is no real solution.

Any idea why this is happening ?
