Introduction

Asynchronous and parallel programming are powerful techniques that can enhance the performance and responsiveness of your applications. In C#, these techniques are made simpler and more accessible through the use of keywords like async and await, and libraries like the Task Parallel Library (TPL).

Imagine you're signed up to help a non-profit company with a software project. Before the project kicks off, you decide to update your programming skills by developing a banking app. To practice your asynchronous programming skills, you're going implement asynchronous versions of helper classes that implement file backup and restore processes.

The topics covered in this module include:

• Introduction to asynchronous programming in C#.
• Implementing asynchronous file input and output in C#.
• Asynchronous access to web resources using HttpClient in C#.
• Implementing parallel programming and asynchronous tasks in C#.
• Managing and handling exceptions in asynchronous and parallel tasks in C#.
• Implementing data parallelism in C# using Parallel.ForEachAsync and Task.WhenAll.

After completing this module, you’ll be able to:

• Implement asynchronous programming in C# using the async and await keywords.
• Perform asynchronous file input and output operations and access web resources asynchronously in C#.
• Use the Task Parallel Library (TPL) in C# for parallel programming and managing concurrent data structures.
• Identify common pitfalls in parallel programming and handle exceptions in async and parallel tasks.
• Implement data parallelism in a C# application as part of a hands-on exercise.
