Introduction

This podcast episode discusses the Task Parallel Library (TPL) in C#, a set of APIs introduced in .NET Framework 4.0 for parallel programming. The speaker aims to explain different methods for simple and efficient parallel processing, highlighting the appropriate tools and when to use them. The episode builds upon a previous episode concerning tasks.

Key Takeaways

• Understanding Tasks: A task represents a unit of work, enabling parallel or synchronous operation. The thread pool manages thread creation and destruction, optimizing application execution.
• Parallel.For and Parallel.ForEach: These methods enable parallel execution of for and forEach loops, respectively. They are blocking, meaning the code only proceeds after completion. They accept options to set the maximum degree of parallelism.
• Task Factory and Async Operations: For asynchronous operations (e.g., database queries, HTTP requests), the Task.Factory.StartNew method creates parallel tasks. Task.WaitAll and Task.WaitAny control task completion, allowing for flexible coordination.
• Task.WhenAll and Task.WhenAny: These provide alternative asynchronous task management, returning tasks themselves for further asynchronous control.
• Exception Handling: Parallel operations may throw AggregateException, masking the root exception. Careful inspection is needed to identify the actual error.
