Cannot set breakpoints in C DLLs used by C ++ / CLI called from C #

Question

I have a native C DLL called by a C ++ / CLI object, which is a ViewModel for a WPA program in C #. I want to set breakpoints in a C DLL. When I try to set them, they are grayed out and a tooltip tells me that the breakpoint will not be deleted at the moment. No characters have been loaded for this document.

In order for the program to start normally, I had to add a custom build step, which copies the DLL, PDB, ILK and LIB files to the intermediate directory of the main C # program. I suspect this is due to a problem.

When I look at the list of loaded modules (Debug - Windows - Modules), after I know that the DLL is loaded, and some functions are executed in it, I do not see the DLL. I see the main C # program and the C ++ / CLI module that calls the C DLL.

All these projects are in one solution - do I need to run a separate instance of the solution for debugging the DLL? Ideally, I want to be able to debug my own DLL, as well as the calling GUI code.

thanks

From the moment you enter the managed code, you need to set the following parameter: In Visual Studio-> login project → properties → Debugging → Enable debugging without changes <- checked
