Writing custom Observable

This recipe will describe how to implement the IObservable<in T> and IObserver<out T> interfaces to get the custom Observable sequence and properly consume it.

Getting ready

To step 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\Recipe2.

How to do it...

To understand how to implement the IObservable<in T> and IObserver<out T> interfaces to get the custom Observable sequence and consume it, 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 more details on how to do this.

3. In the Program.cs file, add the following using directives:

   using System;
   using System.Collections.Generic;
   using System.Reactive.Concurrency;
   using System.Reactive.Disposables...
