<p>Can a flash front end talk to a .net backend?</p>

Yes.
We use
Adobe Flex
to talk to .Net XML web services.
Be careful with complex serialised .Net types (for instance DataSets) - ActionScript can't handle them.
Instead produce simple XML with primitive types.

Flex and ADO.NET Data Services...anyone done it?
```
```
<mx:WebService id="myDataService" showBusyCursor="true">
    <mx:operation name="WebMethodName" resultFormat="object" result="functionFiredOnComplete();"></mx:operation>
</mx:WebService>

public function load():void
{
    myDataService.loadWSDL( "web method's wsdl" );
    myDataService.WebMethodName.send( params );
}

public function functionFiredOnComplete():void
{           
    // get data
    var myData:Object = myDataService.WebMethodName.lastResult;
    ...
```
