If you are looking for information on a free ASP.NET Flash Remoting Solution you have come to the right place.

The Midnight Coders have a product called WebORB® that will meet all of your remoting , real-time messaging (RTMP) and Flex Data Services (AMF0 and AMF3, Data Management, Flex Messaging (pub/sub, push)) needs.

I have used this product's Flash Remotings features extensively on one of my clients sites and I highly recommend it to anyone looking for a Flash Remoting Solution even if they are not doing development in ASP.NET.  WebORB® also comes in Java, Ruby On Rails and PHP versions.

Installation

Installing WebORB® is extremely easy. Just copy its assemblies to your bin folder, copy a few files and folders to your web applications root directory and give a few of them write permissions. The final step is updating your web.config file with its HTTP Handlers.

If you install WebORB® on your server, you have the option of automatically deploying to to a virtual directory.  There seems to be 1 downfall, it appears that it can only be automatically installed to virtual directorys of your default web site. If you are on a server that is hosting multiple web sites, you should just do the manual install.

Using WebORB

One of WebORB's best abilities is that it will parse your Web Applications Assemblies and generate Action Script code for use in your flash movie or JavaScript for your AJAX functions. It can generate code in a variety of formats and styles: Flex Remoting / AS3, Flash Remoting / AS2, ARP Framework / AS2 or AS3, Cairngorm Framework, FlashComm / FMS2, AJAX Client and PureMVC.  It will generate code for anything that your functions  in your assembly returns. Objects, DataSets, strings  etc.
