This chapter takes a look at improving your code's performance using multithreading and parallel programming. In this chapter, we will cover the following recipes:

• Creating and aborting a low-priority background thread
• Increasing the maximum thread pool size
• Creating multiple threads
• Locking one thread until the contended resources are available
• Invoking parallel calls to methods using Parallel.Invoke
• Using a parallel foreach loop
• Cancelling a parallel foreach loop
• Catching errors in parallel foreach loops
• Debugging multiple threads
