Hi I have a WCF Rest 4.0 project. For some reason I have a webservice which should return Json and it does if i hit the endpoint over fiddler but thru firefox or chrome if I type in the address I get xml. Whats going on???

Thanks for any help! Here’s the code.

Web service in question:

  [OperationContract]
  [WebGet(UriTemplate = "",                  
          ResponseFormat = WebMessageFormat.Json,
          RequestFormat = WebMessageFormat.Json)]

        public SomeObject [] GetObjects()
        {
              .....

Object code:

[DataContract]
public class SomeObject
{      
        [DataMember]
        public string Date { get; private set; }

        ....
            public String Site { get; private set; }

    If you are using the .NET 4.0 framework, this is the solution: http://karnicki.eu/2011/02/rest-wcf-net-4-0-service-with-json-jsonp-for-jquery/

    WCF now has JSONP support out of the box with little configuration required.

    Basically you just need to edit/add two config file entries, authenticationMode and StandardEndpoint, and voila, you can view json response from your WCF service in any browser.
