Course description

While .NET environment was receiving another tools connected with concurrency and async programming, reception and feelings were mixed. On one hand the received opportunities were amazing. On the the other, it created the necessity to learn and use totally different elements of the language as well as mechanisms included in .NET itself...

While training engineers during internal and opened trainings, discussing during conferences and browsing the last Dotnetos survey records - in which almost 500 persons from all over the world took part - we’ve noticed that async programming and concurrency are very important for you. This is a topic which engineers related to .NET want to learn. We ourselves share that opinion. Today programming in .NET is almost impossible without understanding of concurrency and async-await technique.

To help you gain that knowledge and understand the basics and rules of async world and concurrency we prepared that Async Expert online course. Async Expert is 10 solid weeks of learning through which we will guide you from the async basics to sync and concurrency collections. To allow you to verify possessed knowledge we prepared suitable homeworks. Extra content from our mentors (Marc Gravel, Daniel Marbach, Steve Cleary) that will help you answer all your extra questions are an additional bonus. Everything will be completed with communication with us via Community - a place where you can talk not only with us, but also with other participants of the course.

Course authors

Szymon Kulec


Dotnetos co-founder, architect, speaker


I like to incorporate an unique combination of Software Architecture and Performance Engineering. With broad knowledge of modern architecture principles, distributed systems, as well as deep understanding of performance principles I make every allocation fear for its existence. I never allocate before noon.

Konrad Kokosa


Dotnetos co-founder, Microsoft MVP, author, speaker


I’m a Pro .NET Memory Management book author and independent consultant, blogger, speaker and a professional Tweeter [see: Twitter]. I share my passion as a .NET trainer, especially in the performance and app diagnosis field.

Łukasz Pyrzyk


Dotnetos co-founder, Microsoft MVP, author, speaker


I’m a software developer interested in performance topics, microservices and optimizations. Moreover, I’m a speaker (more than a blogger) and an active Twitter user.

Course mentors

Marc Gravell


Microsoft MVP, Code geek working at Stack Overflow


Marc has worked extensively with async in .NET from its inception, and async is a key component and consideration in all current library work. He maintains the popular 'Dapper', 'StackExchange.Redis' and 'protobuf-net' libraries, and contributes to many others - and is a long standing Microsoft MVP for these contributions. Moreover, he has been helping to build Stack Overflow for 10 years, specializing in performance, data access and communications in .NET!

Daniel Marbach


Microsoft MVP, Solutions Architect at Particular Software


He can bend minds and spoons with asynchronous programming. He has spoken at several conferences and usergroups about asynchronous programming and quality-driven development. He enjoys weightlifting, dark-roasted coffee, playing with his son and writing more code - at least until midnight when his self-imposed router hack kicks in.

Steve Cleary


Microsoft MVP, "Concurrency in C# Cookbook” author


Top answerer for async/await questions on Stack Overflow. In his free time he's a husband, father… and he programs. Today he uses C#/JavaScript, but remains interested in many different languages.
