    The regular HTTPContext is no longer used with WCF. You want the instance context. 

    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class MyService : IMyService
{
    InstanceContext ic = OperationContext.Current.InstanceContext;
}

    See this link for more details

    You can also enable compatibility mode so your WCF service acts like an old webservice, but you are better off using the InstanceContext
