title: New CRM Connection code causing errors
body: <p>am trying to create a console application that connects to CRM 2016 (On Prem) using the 2016 SDK.</p>
  
  <p>The below code fails. The conn.LastCrmError has the following details and the orgService is null.</p>
  
  <p><strong>Unable to Login to Dynamics CRMOrganizationWebProxyClient is null OrganizationServiceProxy is null OrganizationWebProxyClient is null OrganizationServiceProxy is null.</strong></p>
  
  <pre><code>var connectionString = @"Url=http://xxxx/xxxx/; Username=xxxx; Password=xxxx;";
              CrmServiceClient conn = new CrmServiceClient(connectionString);
              IOrganizationService orgService = conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
  </code></pre>
  
  <p>The connection works when running old code, below, using the 2015 SDK</p>
  
  <pre><code> var connectionString = @"Url=http://wxxxxx/xxxx/; Username=xxxxx; Password=xxxxx;";
              IOrganizationService orgService2 = new OrganizationService(CrmConnection.Parse(connectionString));
              var results = orgService2.Execute(new WhoAmIRequest());
  </code></pre>
  
  <p>Any suggestions on how to resolve this?</p>
