Debugging C# Threads

Question

When I am working on multithreads how can I debug to know which thread causes an abnormal behavior?

Can I use permonitor for debugging, or are there any other tools or debugging facilities that are available?

Answer 2

As an alternative to debugging, you could do thread-related testing. The book The Art of Unit Testing has a section on this in Appendix B. The author mentions three tools (two of which he has a personal interest in):

• Typemock Racer
• Microsoft CHESS
• Osherove.ThreadTester

Answer 3

You can use visual studio to set up breakpoints on certain threads. See here and here for how to do it.
