Mastering C# Concurrency

Overview of this book

Starting with the traditional approach to concurrency, you will learn how to write multithreaded concurrent programs and compose ways that won't require locking. You will explore the concepts of parallelism granularity, and fine-grained and coarse-grained parallel tasks by choosing a concurrent program structure and parallelizing the workload optimally. You will also learn how to use task parallel library, cancellations, timeouts, and how to handle errors. You will know how to choose the appropriate data structure for a specific parallel algorithm to achieve scalability and performance. Further, you'll learn about server scalability, asynchronous I/O, and thread pools, and write responsive traditional Windows and Windows Store applications. By the end of the book, you will be able to diagnose and resolve typical problems that could happen in multithreaded applications.

Chapter 5. C# Language Support for Asynchrony

The Task Parallel Library makes it possible to combine asynchronous tasks and set dependencies between them. In the previous chapter, we reviewed this topic in detail. However to get a clear understanding in this chapter, we will use this approach to solve a real problem—downloading images from Bing (the search engine). Also, we will do the following:

  • Implement standard synchronous approach

  • Use Task Parallel Library to create an asynchronous version of the program

  • Use C# 5.0 built-in asynchrony support to make the code easier to read and maintain

  • Simulate C# asynchronous infrastructure with the help of iterators

  • Learn about other useful features of Task Parallel Library

  • Make any C# type compatible with built-in asynchronous keywords
