Creating asynchronous operations with Rx

This recipe shows you how to create an Observable from the asynchronous operations defined in other programming patterns.

Getting ready

To work through this recipe, you will need Visual Studio 2015. No other prerequisites are required. The source code for this recipe can be found at BookSamples\Chapter8\Recipe6.

How to do it...

To understand how to create asynchronous operations with Rx, perform the following steps:

1. Start Visual Studio 2015. Create a new C# console application project.
2. Add a reference to the Reactive Extensions Main Library NuGet package. Refer to the Converting a collection to asynchronous observable recipe for details on how to do this.
3. In the Program.cs file, add the following using directives:

   using System;
   using System.Reactive;
   using System.Reactive.Linq;
   using System.Reactive.Threading.Tasks;
   using System.Threading.Tasks;
   using System.Timers;
   using static System.Console;
   using static System.Threading.Thread;

4. Add the following code...
