This is because the sourceCodeThe Code provided on the server is optimized by default ). Although you cannot view these values, it does not block single-step execution. In most cases, you may not need to view these values.

Start devenv.exe
Exit

I put this CMD file on my desktop and use this file to start vs when I need optimizations.

3. Start yourProgram.

Now you can see the values of all local and member variables:
