I have a multi-project solution that I was building in Visual Studio 2013 and it was working fine but now that I have upgraded to Visual Studio 2015 I can no longer hit break points in debug mode for any project exect the main project selected as the Startup project in the Project Properties page. I used to be able to click on the other projects and just choose Debug -> Start New Instance. I am getting the error The breakpoint will not currently be hit. No symbols have been loaded for this document. I have tried a lot of things found on Google including:
So what am I missing here? Why can I no longer debug the other projects?
I had a similar problem, when I created a new build configuration. After hunting around settings in VS2015, I noticed that there were no *.pdb files in my build output. Obviously, debugging would not work if there were *.pdb files.
The fix for me was to go into every project's properties -> 'build' page -> click the "advanced" button at the bottom of the page -> In the dialog's 'Output' section, I set "debug info" to equal "full".
Basically, I created a new solution and project and copied all the build properties into the solution that the debugger was not stopping at break points anymore. In addition to the setting above, I also changed the following setting to match the default debug settings:
I solved this problem when checked Options->Debugging->General->Suppress jit optimization on module load. Before I did that I have also unchecked Tools->Options "Projects and Solutions" "Build and Run" "Only build startup projects and dependencies on run". Don't know if that has any reason why it works after suppress jit is unchecked.
My situation was that I have enabled "Optimize code" in the project properties.
