In a thread and another thread tries to lock the mutex in reverse order occurs. One should pay attention to use a mutex to avoid deadlocks. Be sure to complete the operation after releasing the lock.

What's the difference between deadlock and livelock?. Can somebody please explain with examples (of code) what is the difference between deadlock and livelock? multithreading - Simple Deadlock Examples - Stack Overflow. I would like to explain threading deadlocks to newbies.

I have seen many examples for deadlocks in the past, some using code and some using illustrations (like the famous 4 cars). Equally important, c# - await vs Task.Wait - Deadlock?

This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. It's important to note that, difference between racearound condition and deadlock. How to catch SqlException caused by deadlock?
