The Evolution of the .NET Asynchronous API
In February 2002, .NET version 1.0 was released. From this very first release it was possible to build parts of your application that ran asynchronously. The APIs, patterns, underlying infrastructure, or all three have changed, to some degree, with almost every subsequent release, each attempting to make life easier or richer for the .NET developer. To understand why the .NET async world looks the way it does, and why certain design decisions were made, it is necessary to take a tour through its history. We will then build on this in future chapters as we describe how to build async code today, and which pieces of the async legacy still merit a place in your applications today.
