Force Content Types to Json in .NET WebApi

I ran into a situation where I couldn't set the Content-Type header in the http request client I was using. (Crossrider's appAPI.request.post)

The client was either not setting a Content-Type or defaulting to application/x-www-form-urlencoded

If you put the code below in Application_Start you should be able to force form-urlencoded data to the JsonFormatter and by removing the XmlFormatter, Json will also be the default.

HttpConfiguration config = GlobalConfiguration.Configuration;
foreach (var mediaType in config.Formatters.FormUrlEncodedFormatter.SupportedMediaTypes)
