What is a deadlock in C# and how can I prevent it?

A deadlock in C# occurs when two or more threads are blocked forever, each waiting for the other to release a resource. To prevent it, you can use techniques like avoiding nested locks, using a timeout for acquiring locks, or employing lock ordering.

Can you give me an example of a deadlock scenario?

Sure! Imagine two threads: Thread A locks Resource 1 and then tries to lock Resource 2, while Thread B locks Resource 2 and then tries to lock Resource 1. Both threads end up waiting for each other, causing a deadlock.

How can I detect a deadlock in my application?

You can detect deadlocks by using tools like Visual Studio's debugger, which can show you the state of threads and locks. Additionally, you can implement logging to track lock acquisition and release.

What are some best practices to avoid deadlocks?

Best practices include using a consistent lock order, minimizing the scope of locks, and avoiding long-running operations while holding a lock.
