title: Connection issue from latest .Net MongoDb.Driver
body: <p>I created a MongoLab sandbox database. I connected with MongoChef and it works fine.</p>
  
  <p>I installed MongoDB.Driver 2.2.2 through Nuget.</p>
  
  <p>I made some simple C# demo code, but just don't make it work.</p>
  
  <p>The connection string was copied straight from MongoChef where it definitely works!</p>
  
  <p>When trying the same with a local Mongo instance I get the same behaviour. But when trying with driver version 2.1.1 it works locally and with MongoLab! Is the internal connection behaviour changed in some way in 2.2?</p>
  
  <pre><code>    const string connectionString = "mongodb://user:password@ds047095.mongolab.com:47095/dbname";
  
      var client = new MongoClient(connectionString);
  
      var db = client.GetDatabase("dbname");
      var skills = db.GetCollection&lt;Skill&gt;("skill");
      skills.InsertOne(new Skill {SkillName = "TEST"});
  </code></pre>
