debugging in mixed mode with native C++, managed c++ cli, and c# solution
I have a multithreaded project im working on and the startup project is set to ac# project that runs my UI. Then there is a whole series of underlying c++ native projects which are connected to the C# by managed C++/CLI projects. I've enabled in the c# start up project 'Enable Unmanaged debug' and when I attempt to debug the native code, I am able to hit break points I set. However, it hangs after I try to run it again and try to hit a break point again. For example, if I have a loop I try to hit inside it in each iteration, after the second iteration the program hangs and I have to force quit. Im working in Visual Studio 2010. Debugging beginning to prove not too useful at this rate, is there any way to preclude this problem?
When I want to debug native code as well as C++/CLI, I do following:
Allow unsafe code in Build tab and Enable unmanaged code debugging in Debug tab of project properties. Mixed We also had problems debugging complex mixed code applications and found out that the Visual Studio is not that reliable in these situations. My suggestions would be to:
If you're trying to debug a piece of native code try to use a native project as the debugger start-up application. Under the project settings, "Debugging" tab set the "Debugger Type" to "Mixed", for us this helped sometimes (the native project can be a DLL for example, simply set your main Exe as debugging target in the project settings);
Use WinDbg, with it you can debug both managed/unmanaged mixed code applications much more reliably;
I had the same problem when I tried to step into un-managed code from managed, so instead, I got rid of all the breakpoints on the managed side and did the following:
1) open your un-managed source file via File->Open->File (ie my source.cpp)
2) set a breakpoint there
3) start your managed code debugging (Play button)
It should break directly into your un-managed code... at least it works for me...
