Adobe’s Andrew Shorten contacted me following my piece on consuming .NET SOAP with Flex.

He mentioned two free products which integrate Flex with .NET.

Fluorine “provides an implementation of Flex/Flash Remoting, Flex Data Services and real-time messaging functionality for the .NET framework.”

WebORB from Midnight Coders “supports Action Message Format (AMF) version 0 and 3 and can be used to process Flex and Flash Remoting requests. Additionally, WebORB provides an implementation of the RTMP protocol and supports the following real-time messaging and streaming features: Flash Video streaming, video recording, data push, server-to-client invocation and remote shared objects.” There are also implementations of WebORB for Java, PHP and Ruby.

These look useful if you want to take advantage of the faster AMF protocol or use other features like RTMP. The disadvantage: more server-side gunk.
