Asynchronous programming model allows you to run and complete several tasks in a parallel way. Using this model can make your applications more responsive (non-blocking) but make no mistake, it's a tricky road to follow. There are few different models for asynchronous programming such as the old APM Asynchronous Programming Model, the EAP Event-based Asynchronous Pattern and latest one, the TAP TASK-based Asynchronous Pattern which is also the subject of this post. The main class used in TAP pattern is the System.Threading.Tasks.Task which represents asynchronous operations. Asynchronous methods return either Task or Task objects which in turn is not the real result but an ongoing task that is going to be completed at some point. You retrieve the actual result from a Task using it's "Result" property. Let us see some real examples to understand how the TAP asynchronous model works. I will use the Chinook database which you can download and install it to your SQL Server from here. It's not necessary though, you can adjust the respective queries we will write to point your preferred database tables.
