An extremely light-weight, easy to use .Net pub/sub library
Breaking change in 4.0
In an effort to clean up some old bad habits, version 4.0 and beyond no longer has extension methods on object for Publish and Subscribe. The easiest migration solution would be to simply use those methods on the new Hub.Default static instance.

- Provide the ability to do de-coupled communication without having to include some large (and often opinionated) framework when all you want is pubsub
- It should be portable so it can be used pretty much wherever
- Make it stupid simple to use with zero setup

When is it useful?
Pubsub Mac Library Software
In general, the publish/subscribe pattern is great when you want to communicate between pieces of your app without having those pieces being tightly dependent on each other. You might find this article on the subject interesting (it talks specifically about javascript, but the concept applies)
A few cases where I have found this library useful (namely in mobile development):
Mcminnville Library
- Persisting user settings to disk asynchronously
- Posting a message (i.e. Twitter) and using Subscribe to refresh lists, update counts, etc.
- Providing a nice, de-coupled communication medium between Activities and their child Fragments in a Xamarin.Android application.
There are lots of good applications for the publish/subscribe patterns. Have a good one I didn't think of? Let me know
How to use it
First, add a using.
Listen for stuff you might be interested in.
Tell others that interesting things happened.
Stop listening when you don't care anymore.
Some explanation
To keep things simple, yet flexible, PubSub PCL is implemented using core ideas:
- Different kinds of messages are delineated by CLR type.
- This avoids the need to have a list of string constants (or just magic strings), enums, whatever to define what you want to listen for/send.
- This gives us nice strongly-typed data that can be passed from our Publish methods to our Subscribe handlers (i.e. Product above)
