Creating a Service Host? - asp.net-mvc-3

Question

I have created a WCF service.And i am trying to call it from another domain.I have enabled the cross domain option.But my doubt i about how to create a service host??
!-<%# ServiceHost Language="C#" Debug="true" Service="jsonwcf.Service1"
CodeBehind="Service1.svc.cs"
Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory%>
When i am changing the markup to this.it shows servicehost missing.what should i do??
service.cs
namespace jsonwcf
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
[WebInvoke(
Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest
)]
public List<UserDetails> SelectUserDetails()
{
pasDataContext db = new pasDataContext();
List<UserDetails> results = new List<UserDetails>();
foreach (User u in db.Users)
{
results.Add(new UserDetails()
{
UserID = u.UserID,
EmpName = u.EmpName,
Email = u.EmailID,
UserName = u.UserName,
UserRole = u.UserRole,
Password = u.Password,
Telephone = u.Telephone
});
}
return results;
}
[WebInvoke(
Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest
)]
public string ins(string uid, string pwd, string uname, string ename, string tel, string urole, string eid)
{
pasDataContext db = new pasDataContext();
User u = new User();
u.UserID = uid;
u.UserName = uname;
u.UserRole = urole;
u.Telephone = tel;
u.Password = pwd;
u.EmailID = eid;
u.EmpName = ename;
db.Users.InsertOnSubmit(u);
db.SubmitChanges();
return "inserted successfully";
}
}
}
iservice.cs
namespace jsonwcf
{
[ServiceContract(Namespace = "JsonpAjaxService")]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped,UriTemplate = "Service/ins")]
string ins(string uid, string pwd, string uname, string ename, string tel, string urole,string eid);

A .svc should contain something along the following:
<%#ServiceHost ... %>
The error says:
The required directive 'ServiceHost' is missing.
Your .svc begins with:
!-<%# ServiceHost ... %>
Spot the differences.
