title: RestSharp: Could not create SSL/TLS secure channel
body: <p>I'm trying to use RestSharp in Visual Studio 2012 Express on a fresh install of Windows 8.1. The API I'm trying to use supports only RC4-SHA for SSL. The certificate is valid.</p>
  <pre><code>var client = new RestClient();
  client.BaseUrl = &quot;https://teststore.mybigcommerce.com/api/v2/&quot;;
  client.Authenticator = new HttpBasicAuthenticator(&quot;username&quot;, &quot;key&quot;);
  
  var request = new RestRequest();
  request.Resource = &quot;time.json&quot;;
  
  IRestResponse response = client.Execute(bcrequest);
  </code></pre>
  <p>I keep getting an error from the client: <code>The request was aborted: Could not create SSL/TLS secure channel</code>. I thought there were certificate problems, until I finally took a packet capture and discovered there were no cipher suites in common. RC4-SHA is not available on the client end. After installing Windows 7 and running the exact same code, the problem goes away.</p>
  <h3>Why is RC4-SHA unavailable in RestSharp on Windows 8.1?</h3>
