Add the following code snippet inside the Main method:Task t = AsynchronousProcessing(); t.Wait();

Run the program.

How it works...

To be compatible with the await operator, a type should comply with a number of requirements, stated in the C# 5.0 specification. If you have Visual Studio 2012 installed, you may find the specifications document inside the C:\Program Files\Microsoft Visual Studio 11.0\VC#\Specifications\1033 folder (assuming you have used the default installation path).

In paragraph 7.7.7.1, we find a definition of awaitable expressions:

The task of an await expression is required to be awaitable. An expression t is awaitable if one of the following holds:

t is of compile time type dynamic

t has an accessible instance or extension method called GetAwaiter with no parameters and no type parameters, and a return type A for which all of the following hold:A implements the interface System.Runtime.CompilerServices.INotifyCompletion (hereafter known as INotifyCompletion for brevity)

A has an accessible, readable instance property IsCompleted of type bool

A has an accessible instance method GetResult with no parameters and no type parameters
