Do I need IIS7 to use binary with HTTP for WCF?
No, all you need is a custom binding because we don’t include a standard binding with that configuration out of the box.
Here’s a quick example of putting binary and HTTP together with either code or configuration:
BinaryMessageEncodingBindingElement encoding = new BinaryMessageEncodingBindingElement();HttpTransportBindingElement transport = new HttpTransportBindingElement();Binding binding = new CustomBinding(encoding, transport);
<bindings><customBinding><binding name="BinaryHttpBinding"><binaryMessageEncoding /><httpTransport /></binding></customBinding></bindings>
You could also make a subclass of Binding if you didn’t want to build a custom binding every time, but no special version of IIS is required.
