Visual Studio 2022 - Debugger Stops at Unreachable Code with Invalid Configuration

visual-studio debugging conditional-compilation C#

I'm collaborating on a project where I'm optimizing some code but I'm updating my dependencies and I'm not sure how to approach I'm currently working with an scenario in Visual Studio 2022 where the debugger unexpectedly stops at unreachable code during execution..... I have a simple console application where I use conditional compilation directives, and sometimes it hits breakpoints in sections that should be excluded based on the build configuration. My project is set to use the 'Debug' configuration, and I have the following code snippet: ```csharp #if DEBUG Console.WriteLine("Debug mode"); #else Console.WriteLine("Release mode"); #endif ``` However, when I run the debugger, it breaks on the `else` branch even though I am sure I'm running it in 'Debug' mode. I've checked that the preprocessor symbols are correctly set in the project properties under the 'Build' tab. Here’s what I’ve tried to resolve the scenario: 1. Clean and rebuild the solution. 2. Deleted the `.vs`, `bin`, and `obj` folders, then rebuilt. 3. Verified that no other configurations are interfering with the build process. 4. Checked the output window for any warnings or errors during the build. Despite all this, the debugger still stops in the `else` section, which should never be executed in 'Debug' mode. I've even added logging before the conditional compilation directives to see the flow of execution, and it confirms that it should never reach that point. What could be causing the debugger to behave this way? Is there a configuration setting I am missing, or could it be a bug in Visual Studio itself? I would appreciate any insights or suggestions on how to troubleshoot this further. I'd really appreciate any guidance on this. Any ideas how to fix this?
