This dotnet core project contains a simple implementation of an in-memory pub-sub pattern (PubSubSample.Messaging) and a sample application that uses the messaging library.

In this library, we have generic interfaces for publisher and subscription (IPublisher<T> and ISubscription<T>). In this design, the Type T determines the relationship between these two. This means published T1 messages will be received by subscribers of a T1 message but not by subscribers of a T2 message.

The sample application (PubSubSample.SampleApp) accepts first name and last name, then displays two different formats of the complete name. Its usage of the PubSubSample.Messaging library is as follows:

• When the name is read from console, a Name object is published.
• A display object is subscribed to the Name message and displays it in different formats once received.
