You are creating an ASP.NET web application that hosts several Windows Communication Foundation (WCF) services. The services have ASP.NET Compatibility Mode enabled. Users authenticate with the Web application by using a cookie-based ASP.NET Forms Authentication model. You add a service file named Authentication.svc that contains the following code segment: <%@ ServiceHost Service="System.Web.ApplicationServices.AuthenticationService" Factory="System.Web.ApplicationServices.ApplicationServicesHostFactory" %> You need to ensure that users can access the WCF services without having to re-authenticate.
