Using Rx, developers represent asynchronous data streams with Observables , query asynchronous data streams using LINQ operators , and parameterize the concurrency in the asynchronous data streams using … Posted 13 February 2014 - 3 min read. First of all I will create a new instance of class Subject from System.Reactive.Subjects namespace. As a result different subscribers will handle the same message differently. Hence instead of existing implementation where an Action delegate is passed from Main method to Listen method of the BookingConsumer class, I will update the BookingConsumer to take IBookingStream as a constructor parameter. For instance, Reactive Extensions for .NET provides a custom awaiter for awaiting IObservable instances in async methods.

Als Lösung … First method is Publish, which is used for publishing messages into the Rx stream. Implementing Reactive Extensions. It brings no new capabilities but does bring new ways to do things (much like Linq), while writing less code and with more elegance.
