I have a Windows Service which self hosts a WCF service. The Windows Service contains all of the logic. The WCF Service call using ajax but browsers sending error like Method Not allowed and No Access-Control-Allow-Origin. using this

<pre>WebServiceHost host = new WebServiceHost(typeof(Generat), new Uri("http://localhost:8800/GetClient"));
            ServiceMetadataBehavior smb = new Ser<code></code>viceMetadataBehavior();
            smb.HttpGetEnabled = true;
            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(smb);
            host.Open();

What I have tried:

self host wcf service successfully and windows service also start properly but when call from another web application give error
and call using ajax

$.ajax({
                url: 'http://localhost:8800/BCon/GetClient',
                type: 'GET',
                contentType: 'application/json;charset-uf8',
                dataType: "json",
            }).success(function (data) {
               alert(data);
            }).error(function (error) {
                alert(error);
            });
