Newtonsoft WebDialog has gotten to the point where I feel it is ready to begin beta testing.
Documentation is still largely work in progress but there are installation instructions and intellisense for all new objects, as well as a quickstart guide on this website. The WebDialog beta is fully functional when developing on your own computer.
If you encounter any bugs or have any comments I'd love to hear them. You can either use the support request form or leave a comment here.
