Disable JSON Support in ASP.NET MVC Web API

Question

In the creation of our new MVC Web API-based service, we want to focus on XML to begin with and add JSON functionality later as an enhancement, using the full release with nativ

Answer 1

All you have to do is to remove JSON media formatters.

// Identify JSON formatters in global config.
var jsonMediaTypeFormatters = GlobalConfiguration.Configuration.Formatters
    .Where(x => x.SupportedMediaTypes
    .Any(y => y.MediaType.Equals("application/json", StringComparison.InvariantCultureIgnoreCase)))
    .ToList();

// Remove formatters from global config.
foreach (var formatter in jsonMediaTypeFormatters)
{
    GlobalConfiguration.Configuration.Formatters.Remove(formatter);
}

Answer 2

There's an even shorter option, because there can be only one Json formatter and the MediaTypeFormatterCollection exposes it as a property. Available since Web API 2 (maybe also in v1, not sure).

Formatters.Remove(controllerSettings.Formatters.JsonFormatter)
