Debugging a multi-threaded application

Question

I have inherited an application that throws up 100 threads at the start. This makes my debugging life extremely tricky. Is there a way of getting Visual Studio to follow one thread?

Answer 1

Have you tried using the 'Threads' window in Visual Studio (in Debug / Windows menu) ?

You can freeze threads and switch between them

Answer 2

If possible, I suggest that in Debug mode you limit the number of threads that are created, to a much more manageable number, e.g., 3. That way you can still can diagnose bugs due to interaction between threads, but you are not completely snowed under.
