C# Concurrency: Asynchronous and Multithreaded Programming teaches you to harness the power of multithreading and async/await to get maximum speed from your code. Nir Dobovizki, a seasoned C# veteran with over 30 years of high-performance programming experience, is here to share his deep knowledge and expert techniques with you. Say goodbye to frustrating pitfalls and impossible-to-find bugs that slow down your applications. Nir's careful approach will teach you how to navigate these challenges with ease, allowing you to achieve lightning-fast performance like never before!
about the technology
Concurrency is a developers’ secret weapon for maximizing an application's performance. Using asynchronous and multithreaded programming techniques, you can seamlessly execute multiple tasks simultaneously, without sacrificing speed or quality. However, concurrency is notoriously challenging to implement correctly due to the potential for race conditions, deadlocks, and other synchronization issues, and even an experienced developer can make mistakes that undermine their code’s speed and introduce bugs that take forever to find.
Multithreading and asynchronous programming are two ways to make the computer do more than one thing at the same time. Multithreading is about making it seem like the computer is doing multiple things (more things than the number of CPU cores) at the same time and asynchronous programming is about better utilizing the CPU in all the situations that would normally cause the CPU to wait. Making the computer do more than one thing at the same time is extremely useful; it can help keep native apps responsive while they work, and it is required to write high performance servers that can communicate with multiple clients.
Each of those techniques is totally adequate for creating a responsive client application of server with a handful of clients – but together they can be used to take performance to the next level and have servers that can respond to thousands of clients at the same time. Multithreading and asynchronous programming are not only immensely powerful, but also, unfortunately, unintuitive, difficult to use correctly and full of pitfalls.
