InvalidOperationException when using soap client

I've added as wsdl file using the add servece reference dialog in vs2008.

MyService serviceproxy = new MyService();

When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german):

Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract.

Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.

EDIT here is what's in my app.config:

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="MyServiceBinding" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    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="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
    </system.serviceModel>

Edit: Sorry, my first answer was wrong. For the client you need:

ChannelFactory<Interface> factory = new ChannelFactory< YourServiceInterface >(new basicHttpBinding(), new EndpointAddress(new Uri("http://localhost:8888/YourService")));
YourServiceInterface proxy = factory.CreateChannel();

Check your config file - web.config if you're in a ASP.NET web app or web site, app.config if it's a Winforms or console app.

There ought to be some config for your WCF service in there - anything below <system.serviceModel> would be fine. If not - add the necessary info to your config!

OK, so if you want to specify your endpoint URL in code, you need to do this when you instantiate your client proxy class - otherwise, it'll go look in config. Using this code snippet, you'll be using the http binding configuration settings from app.config, and specify the URL separately, in code:

BasicHttpBinding binding = new BasicHttpBinding("MyServiceBinding");
EndpointAddress address = new EndpointAddress(new Uri("http://localhost:8888/YourService"));

MyService serviceproxy = new MyService(binding, address);

That way, the basicHttpBinding object will read the settings from the config under the bindings with a name=MyServiceBinding.

You need something like this in your config:

<client>
  <endpoint binding="basicHttpBinding" 
    bindingConfiguration="MyServiceBinding" contract="ServiceName.ServiceInterface"
    name="MyServiceEndpoint">
  </endpoint>
</client>

inside your tag

I just read your comment.

So Removed the address from the endpoint config.

You can choose to specify the endpoint completely in your code or just the address like this:

MyServiceClient proxy = new MyServiceClient();
proxy.Endpoint.Address = new EndpointAddress ("http://addressto your service"); //<-- address
