Steps to automatically return JSON in a Visual Studio web API1. Open your Visual Studio

After setting up a Web API project in Visual Studio 2013, I noticed that when I visit a sample restful URL in my browser, such as http://localhost/values/5, it returns XML. Is there a way to configure it so that it defaults to returning JSON instead of XML? Should I make changes in my Global.asax file for this? Appreciate any insights on this matter!

Answer №1

When using Web API, the default return format for the service document is in AtomPub format. If you want to request JSON instead, simply include the following header in your HTTP request:

Accept: application/json

Alternatively, you have the option to completely remove support for XML media type in Global.asax by modifying the WebApiConfig class as shown below:

public class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml");
        config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType);
    }
}
