Changes to Postal.NET

I made a few changes to my Postal.NET library: it is now released under the LGPL license, but that’s not the most important.

As of now, subscriptions do not prevent a subscriber from being garbage collected: I am using GCHandle instead of the actual Action<Envelope> delegate. I also added a minor convention that uses a class’ namespace as the channel and its name as the topic.

The most important is… it is now available in Nuget as https://www.nuget.org/packages/Postal.NET!

Enjoy, and let me know about it!
