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    lt serviceHostingEnvironment multipleSiteBindingsEnabled  true   gt    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    lt system serviceModel gt           lt bindings gt               lt wsHttpBinding gt                   lt 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  gt                       lt readerQuotas maxDepth  32  maxStringContentLength  8192  maxArrayLength  16384                          maxBytesPerRead  4096  maxNameTableCharCount  16384    gt                       lt reliableSession ordered  true  inactivityTimeout  00 10 00                          enabled  false    gt                       lt security mode  None    gt                   lt  binding gt               lt  wsHttpBinding gt           lt  bindings gt           lt client gt               lt endpoint address  http   id web Services EchoService svc  binding  wsHttpBinding                  bindingConfiguration  WSHttpBinding IEchoService  contract  IEchoService                  name  WSHttpBinding IEchoService  gt                   lt identity gt                       lt servicePrincipalName value  host mikev-ws    gt                   lt  identity gt               lt  endpoint gt           lt  client gt       lt  system serviceModel gt

We store our URLs in a database and load them at runtime.

public class ServiceClientFactory<TChannel> : ClientBase<TChannel> where TChannel : class
{
    public TChannel Create(string url)
    {
        this.Endpoint.Address = new EndpointAddress(new Uri(url));
        return this.Channel;
    }
}

Implementation

var client = new ServiceClientFactory<yourServiceChannelInterface>().Create(newUrl);

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

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
