Observer Design Pattern (An Introduction for .NET Developers [.NET 6 and C# 10])

[@F2H16]

Your vids are awesome.But if you could show some diagrams to explain the notion behind a concept that would make your tutorials even more appealing.

thanks for the great video. Looks like the *event* mode also performs the similar Observer Design Pattern job, could you let us know the benefit of using the IObservable/IObserver interface?

@William Liu, the main benefit of IObservable/IObserver implementation is that the entire registration between the subject and the observer relationship is invested. And that provides an opportunity to further decouple the two.
So we can create a separate event manager class that can manage the relationship between the subject (IObservable) and the observer (IObserver).

@@DotNetCoreCentral Thank you for clarifying it!

Thanks for the nice content. By the way, internal is the default if no access modifier is specified in c# not private.

For classes the default is internal. For class members the default is private.
