1. Unfortunately I cannot help you with this one I need more information about that content. I just don't see what logic is behind it what does input represent and what is an output to it... 2. Every element in the XML tree has a name (the element type name or in other words a tag name) and every element must be enclosed in a matching pair of tags so that is why it occupies more content with its information representation. Or to put it simply in JSON you have: { Hello:World } In XML you have: World So... JSON is smaller... 3. You can find a detailed comparison here  but in short WCF is primarily focused on creating SOAP based services while Web API is only focused on creating REST based services.
