To receive a pure JSON string, without it being wrapped into an XML, you have to write the JSON string directly to the HttpResponse and change the WebMethod return type to void. [System.Web.Script.Services.ScriptService] public class WebServiceClass : System.Web.Services.WebService { [WebMethod] public void WebMethodName() { HttpContext.Current.Response.Write(“{property: value}”); } }
I found that if I make the default constructor of my class that my webmethod returns anything other than public it will not serialize the __type:ClassName portion. You may want to declare your default constructor protected internal ClassName() { }

The low-level answer here is that a Web Reference will create a client proxy class that allows your code to talk to a Web Service that is described via WSDL and communicates via SOAP or HTTP GET (other posters indicate that it is only ASMX, but Web References can also talk to Java-based Web Services … Read more
Keith Elder nicely compares ASMX to WCF here. Check it out. Another comparison of ASMX and WCF can be found here – I don’t 100% agree with all the points there, but it might give you an idea. WCF is basically “ASMX on stereoids” – it can be all that ASMX could – plus a … Read more
