Async Await and the Generated StateMachine
https://www.codeproject.com/Articles/535635/Async-Await-and-the-Generated-StateMachine
这篇文章是在code project上，写了async的代码，直接反编译看编译器的源码了
C# Async: What is it, and how does it work?
https://www.red-gate.com/simple-talk/dotnet/net-tools/c-async-what-is-it-and-how-does-it-work/
这篇文章在red-gate的simple talk上，先自己写了一个状态机来说明如何解决异步编程问题，后面才转到async反编译源码分析
C# Under the Hood: async/await
https://www.markopapic.com/csharp-under-the-hood-async-await/
这个文章先写了一个可以被await的class，分析如果想要被await的话，需要满足哪些条件，然后反编译分析源码
这个文章发表在一个个人网站上，作者还有一篇分析依赖注入的https://www.markopapic.com/dependency-injection-tradeoffs/
