Converting WSE example code to WCF

Question
I am new to both WSE and WCF and I am trying to consume a web service using WCF but all the example documentation is for VS2005 + WSE. This web service uses WS-Security 1.0. I have added a service reference through visual studio but I am at a loss on how to do the equivalent of the code below in WCF:
// 1. Initialize the web service proxy
PartnerAPIWse integrationFramework = new PartnerAPIWse();
// 2. Set the username/password. This is using the Username token of WS-Security 1.0
UsernameTokenProvider utp = new UsernameTokenProvider("username", "password");
integrationFramework.SetClientCredential<UsernameToken>(utp.GetToken());
// 3. Declare the policy
Policy policy = new Policy(new UsernameOverTransportAssertion());
integrationFramework.SetPolicy(policy);
Solution
After spending a day doing some experimentation I figured out how to convert this code. The key was setting up the bindings on the WCF proxy that VS2008 makes correctly.
- Add a service reference pointing to the WSDL
Open App.config / Web.config and locate the system.serviceModel section. Change the security mode on the default soapbinding to be TransportWithMessageCredential. Here is what my file looked like after the change:
<basicHttpBinding> <binding name="SoapBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding>
Change the example code above to look like this
Dim integrationFramework As New SoapClient() integrationFramework.ClientCredentials.UserName.UserName = "username" integrationFramework.ClientCredentials.UserName.Password = "password"
TransportWithMessageCredential is equivalent to UsernameOverTransportAssertion policy under WSE 3.0
