c# - Cannot find .cs files for debugging .NET source code

Question

I tried setting up debugging the .NET source by following this MDSN walkthrough. The Symbol cache is setup properly, as is the check 'Enable .NET Framework source stepping'.

But subsequently, whenever I want to step into .NET code, I am prompted to specify the location of the relevant cs file. The error message is You need to find <filename>.cs to view the source for the current call stack frame and The debugger could not locate the source file <filename>.cs.

I am offered to browse for the file (but I don't have it) or view a disassembly (but I don't want that).

How to step into the .NET source code?

Answer 1

Well, in my case I was not trying to debug the .Net framework, but I was getting the same error: Cannot find .cs files for debugging .NET source code. So I had to turn on the "Enable just my code" option under:
Tools -> Options -> Debugging -> General -> Enable just my Code

Per MS docs:

You can configure Visual Studio to automatically step over system, framework, and other non-user calls and collapse those calls in the call stack window.
