Could not find default endpoint element that references conctract

I'm trying to work with Amazon's Web Services.  I have successfully used VS2008 to create the Service Reference.  It auto generated the proxy Reference.cs and app.config files successfully.  

When I execute this line:

AWSECommerceServicePortTypeClient ecs = new AWSECommerceServicePortTypeClient();

I get the error:

Could not find default endpoint element that references contract 'AmazonWebService.AWSECommerceServicePortType' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

Here is the app.config file:

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="AWSECommerceServiceBinding" 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>
        <client>
            <endpoint address="http://soap.amazon.com/onca/soap?Service=AWSECommerceService"
                binding="basicHttpBinding" bindingConfiguration="AWSECommerceServiceBinding"
                contract="AmazonWebService.AWSECommerceServicePortType" name="AWSECommerceServicePort" />
        </client>
    </system.serviceModel>

I have tried putting in the full namespace in the contract field as "Rodunu.Services.Amazon.AmazonWebService.AWSECommerceServicePortType" and receive the same error.

All help is appreciated.
