.net - Calling a web service that requires basic http authentication from wcf client

Question

I have a wsdl from a web service, I generated the wcf proxy. No problem.

But I can not get my head around how to pass the user name and password. The webservice requires basic authentication - only username and password.

Any help ?

Is Basic authentication configured in configuration file? Do you need to pass only credentials or do you also need secured transport (HTTPS)?

First you need to set up binding to support Basic authentication

Setup for HTTP binding:

<bindings>
  <basicHttpBinding>
    <binding name="BasicAuth">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

Setup for HTTPS binding:

<bindings>
  <basicHttpBinding>
    <binding name="BasicAuthSecured">
      <security mode="Transport">
        <transport clientCredentialType="Basic" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

Client endpoint has to use defined configuration like:

<client>
  <endpoint address="..." 
            name="..." 
            binding="basicHttpBinding" 
            bindingConfiguration="BasicAuth" 
            contract="..."  />
</client>

Then you have to pass credentials to the proxy:

proxy = new MyServiceClient();
proxy.ClientCredentials.UserName.UserName = "...";
proxy.ClientCredentials.UserName.Password = "...";
