WCF and the WebHttpBinding

One new binding with Orcas Beta 2 and WCF I’m really excited about is the new WebHttpBinding – got to love the Json all built in 🙂 Plus the new WebGet attribute to get your REST services on the way. One thing I thought was missing was the ability to be able to specify a callback method when you call a service and want some Json back (I couldn’t find an option/see anything in Reflector but maybe there is a way to get it in there?). The point being that if a browser does an HTTP GET using a script tag then it may want to put the Json it gets back through a callback function or assign it to some variable – not just dump the Json into the page 🙂

So to get this built in I made an http module which you can get from here. When you call the service and attach a query string parameter of callback=your_javascript_function_name_here it will wrap the Json getting spat out in the function specified 🙂
