Hands-On Design Patterns with C# and .NET Core

Reactive and IObservable

In the previous section, we discussed reactive programming and went through its model. In this section, we will discuss the Microsoft implementation of reactive programming. In response to reactive programming in .NET Core, we have various interfaces that provide a way to implement reactive programming in our application.
