Duplex is an MVVM framework for developing realtime web application using the MVVM pattern, and a full duplex connection between the browser and server.

Duplex is currently in it's humble beginnings and at this stage is little more than a proof of concept, however, it is a pretty cool example so download it and check it out if you like.

Duplex is build using some of the most amaizing new technologies.

1. SignalR handles the connectivity between the browser and server.Easily my favorite Open Sorce project right now.
2. Knockout this javacript library handles atomatic binding on the client side, also truley remarkable. if you are a web developer this library will really make you life better.
3. Reactive Extentions This if the future of asyncronous programming on the .NET platform. If you don't know about it now you will soon. Rx has both a server side and client side library that allows you to write link queries against asyncronous streams of data (to put it mildly).

The combination of these technologies creats truley amaizing results, and the goal of DuplexMVVM is to crate a layer of abstraction that will both reduce the learning curve, and provide a powerful framework for building realtime applications for the web.
