title: Value cannot be null. Parameter name: uri
body: <p>I get the following error when I am trying to invoke my Adobe Livecyle Soap service:</p>
  
  <p>Value cannot be null. Parameter name: uri</p>
  
  <p>The strange thing is that I don't have any parameter named "uri". I can't debug this error since the service can't even start. The error message is all I've got. </p>
  
  <p>Here is the code, that I pass the parameter:</p>
  
  <pre><code>BasicHttpBinding binding = 
      new BasicHttpBinding(BasicHttpSecurityMode.Transport);
  binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
  
  LetterService.LETTER_APPLICATIONS_Client client = 
      new LetterService.LETTER_APPLICATIONS_Client(
            binding, 
            new EndpointAddress(
                  System.Configuration.ConfigurationManager.AppSettings["URL"]));
  </code></pre>
