Answer 1

Your WCF server should be configured to enable jsonp with CrossDomainScriptAccessEnabled

Here is a simple working example

Server:

Task.Run(() =>
{
    var uri = new Uri("http://0.0.0.0/test");
    var type = typeof(TestService);
    WebServiceHost host = new WebServiceHost(type, uri);
    WebHttpBinding binding = new WebHttpBinding();
    binding.CrossDomainScriptAccessEnabled = true;
    host.AddServiceEndpoint(type, binding, uri);


    host.Open();

});

[ServiceContract]
public class TestService
{
    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    public string Hello()
    {
        return "Hello World";
    }
}

And this is the javascript code

Now you can test it from your browser

http://localhost/test/hello

and

http://localhost/test/hello?callback=myfunc
