Observer Pattern in .NET

Introduction I have previously written few posts about delegates, .NET Events, Events Args to show that similar to real world events, we can use this concept in our code and how useful they are in certain scenarios. In this post, we will see that those types are a good candidate for implementing observer pattern without … Read more

Delegates, can’t live with them, can’t live without them.

Introduction There is a famous quote by Jim Henson: “If you can’t beat them. Join them”. It’s possible to write code for years without deliberately using delegates.

We saw how we can define events, raise and finally handle events. If you haven’t already then I will suggest to read that post for the background and … Read more
