Hope this helps Action defines your input uri for the soap operation for your service method.
Reply Action defines the output uri for your service method.

WCF ReplyAction="*" breaks metadata

I think the issue was by ths following , Setting ReplyAction="*" for an OperationContract means the WsdlExporter (which publishes the metadata) will ignore that Operation. Setting any other value will fix it.

This might help you You only need the Action / ReplyAction properties if you want to customize those values in the messages (and they're reflected in the WSDL). If you don't have them, the default is + + for the Action, and + + + "Response" for ReplyAction.
The code below prints out the Action/ReplyAction properties of all operations in the service.
code :
public class StackOverflow_6470463
{
    [ServiceContract(Namespace = "http://schemas.mycompany.com/", Name = "MyService")]
    public interface IMyService
    {
        [OperationContract(Name = "MyOperation")]
        string MyOperation(string request);
    }
    public class Service : IMyService
    {
        public string MyOperation(string request) { return request; }
    }
    public static void Test()
    {
        string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
        ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
        host.AddServiceEndpoint(typeof(IMyService), new BasicHttpBinding(), "");
        host.Open();
        Console.WriteLine("Host opened");

        foreach (ServiceEndpoint endpoint in host.Description.Endpoints)
        {
            Console.WriteLine("Endpoint: {0}", endpoint.Name);
            foreach (var operation in endpoint.Contract.Operations)
            {
                Console.WriteLine("  Operation: {0}", operation.Name);
                Console.WriteLine("    Action: {0}", operation.Messages[0].Action);
                if (operation.Messages.Count > 1)
                {
                    Console.WriteLine("    ReplyAction: {0}", operation.Messages[1].Action);
                }
            }
        }

        Console.Write("Press ENTER to close the host");
        Console.ReadLine();
        host.Close();
    }
}
Can the Action and ReplyAction property of OperationContractAttribute be the same?

To fix the issue you can do Just to follow up on my own question in case it's helpful to others... I did proceed with using the same value for Action and ReplyAction.
Many SOAP implementations ignore the actions so it's less relevant, but WCF does use this value to route a message to the operation on a service. Setting both of the values to the same thing doesn't cause any issues because no system processes both the request and the response so there's nothing ambiguous about it.

this will help No way, you can not detect the current browser's proxy settings.
The solution could be adding an option window to your application. In this case, users can define new proxy entries and your application can use it.
