Asynchronous Programming in C#

Kort om undervisningen

Discover the practical power of Asynchronous Programming in C#, in this up-to-date course covering C# 11 and .NET 7. Gain the expertise needed to seamlessly architect and implement responsive, efficient and scalable applications.

In today’s dynamic software landscape, mastering asynchronous programming is more and more essential for crafting faster, hardware-optimized applications. As multi-core CPUs are now standard, parallel processing is the key to unlocking performance. While the demand for responsive interactions with remote services has only heightened the immense value that asynchronous programming can bring.

In this comprehensive two-day course for seasoned C# and .NET developers seeking to master asynchronous programming, we will cover a diverse set of libraries and tools, from threads and locks to advanced features like concurrent collections, PLINQ, Tasks, and async/await. Each library’s purpose will be demystified, helping you to pinpoint the right solutions to specific challenges.

The course offers clear, accessible explanations of the underlying theory and key terms, as well as give hardware-level insights to solidify your grasp of the material. There will also be hands-on exercises that enable you to master and apply the intricacies of asynchronous programming.

By the end of this course, you will be empowered to use asynchronous techniques to deeply optimize the efficiency, scalability and responsiveness of your applications.
