                    hi,
I am New to window Store app,
I have web service like below
 public AuthHeader AuthHeaderValue;
 [SoapHeader("AuthHeaderValue", Required = true)]
 [WebMethod]
 public bool Authentiction()
 {
 if (AuthHeaderValue.Username == "anji" && AuthHeaderValue.Password == "anji")
 {
 return true;
 }
 return false;
 }
public class AuthHeader: SoapHeader
 {
 public string Username;
 public string Password;
 
 }
 ---------------------------------------------------------------------
 and My web service method soap requset like below ,
<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Header> <AuthHeader xmlns="http://tempuri.org/"> <Username>string</Username> <Password>string</Password> 
</AuthHeader> </soap:Header>
 <soap:Body> <Authentiction xmlns="http://tempuri.org/" />
 </soap:Body> 
</soap:Envelope> 
And I wanna pass values to Authheader
when add reference to my app,
It is not allowing me to pass values through webservice reference object.......................
 ServiceReference1.AuthenticationSoapClient service = new ServiceReference1.AuthenticationSoapClient();
 ServiceReference1.AuthHeader authentication = new ServiceReference1.AuthHeader();
 authentication.Username = "anji";
 authentication.Password = "anji";
 service.AuthHeaderValue= authentication;
 
Is there any other way to pass values through metro app.....
