WCF change endpoint address at runtime

Question

I have my first WCF example working. I have the host on a website which have many bindings. Because of this, I have added this to my web.config.

<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/> 

This is my default binding http://id.web, which works with the following code.

EchoServiceClient client = new EchoServiceClient(); litResponse.Text = client.SendEcho("Hello World"); client.Close(); 

I am now trying to set the endpoint address at runtime. Even though it is the same address of the above code.

EchoServiceClient client = new EchoServiceClient(); client.Endpoint.Address = new EndpointAddress("http://id.web/Services/EchoService.svc");   litResponse.Text = client.SendEcho("Hello World"); client.Close(); 

The error I get is:

The request for security token could not be satisfied because authentication failed.  

Please suggest how I may change the endpoint address at runtime?

Additional here is my client config, requested by Ladislav Mrnka

 <system.serviceModel>         <bindings>             <wsHttpBinding>                 <binding name="WSHttpBinding_IEchoService" closeTimeout="00:01:00"                     openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"                     bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"                     maxBufferPoolSize="524288" maxReceivedMessageSize="65536"                     messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"                     allowCookies="false">                     <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"                         maxBytesPerRead="4096" maxNameTableCharCount="16384" />                     <reliableSession ordered="true" inactivityTimeout="00:10:00"                         enabled="false" />                     <security mode="None" />                 </binding>             </wsHttpBinding>         </bindings>         <client>             <endpoint address="http://id.web/Services/EchoService.svc" binding="wsHttpBinding"                 bindingConfiguration="WSHttpBinding_IEchoService" contract="IEchoService"                 name="WSHttpBinding_IEchoService">                 <identity>                     <servicePrincipalName value="host/mikev-ws" />                 </identity>             </endpoint>         </client>     </system.serviceModel> 

Answer 1

So your endpoint address defined in your first example is incomplete. You must also define endpoint identity as shown in client configuration. In code you can try this:

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws"); var address = new EndpointAddress("http://id.web/Services/EchoService.svc", spn);    var client = new EchoServiceClient(address);  litResponse.Text = client.SendEcho("Hello World");  client.Close(); 

Actual working final version by valamas

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws"); Uri uri = new Uri("http://id.web/Services/EchoService.svc"); var address = new EndpointAddress(uri, spn); var client = new EchoServiceClient("WSHttpBinding_IEchoService", address); client.SendEcho("Hello World"); client.Close();  

Answer 2

This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.

var myBinding = new BasicHttpBinding(); myBinding.Security.Mode = BasicHttpSecurityMode.None; var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/"); client = new ClientTest(myBinding, myEndpointAddress); client.someCall();
