title: Best way for Flex to communicate with C# backend?
body: <p>What is the best way for flex frontend to communicate with backend writted in C#? The only communication channel in HTTP, so no custom sockets.</p>
  
  <p>I used SOAP in the past, but am concerned about performance since the large overhead of xml, and this application I'm currently working on will be pretty data intensive.</p>
  
  <p>Anything that supports easy setup and transparent marshaling/unmarshaling is OK.</p>
  
  <p>Is there something as BlazeDS for .net?</p>
