Web Service with Windows Authentication with Soap Client

I need to access a webservice from a c# forms app.

The webservice needs Windows Authentication.

I use the following code:

ServiceDeskSoapClient sd = new ServiceDeskSoapClient();
sd.ClientCredentials.UserName.UserName = @"mydomain\myusername";
sd.ClientCredentials.UserName.Password = "mypassword";
sd.MyMethod();

But get the following error:

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.

How do I correctly set the credentials so it uses windows auth, not anonymous?

Add the following inside the <binding> section in the client's app.config:

<security mode="TransportCredentialOnly">
  <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm="" />
  <message clientCredentialType="UserName" algorithmSuite="Default" />
</security>

In case anyone still needs this, I had the pleasure of figuring it out today. It really was quite simple:

var server = new MySoapClient();
if (server.ClientCredentials != null)
{
    server.ClientCredentials.Windows.AllowNtlm = true;
    server.ClientCredentials.Windows.ClientCredential = new NetworkCredential("MyUsername", "MyPassword", "MyDomain");
}
