In the previous C # Basic Knowledge series, I only introduced the main features from C #1.0 to C #4.0. the launch of NET 4.5 has added new features for C #-The async and await keywords in C #5.0. These two keywords simplify asynchronous programming and simplify the process, or because the compiler has done more work for us, let's take a look at the complex work behind the compiler.

Brief introductionThreading is a technique that can execute multiple code paths in one application at the same time. While new technologies such as operands and GCD provide a more modern and efficient tool for concurrency,OS X and iOS also provide interfaces to create and manage threads.This article reveals the thread packs available in OS X and shows how to use them. This article also describes techniques for supporting threading and multithreaded code synchronization in an application. Importa
