title: Cannot find FindOne method in MongoDB C# driver 2.2.2
body: <p>I am trying to compile following code</p>
  
  <pre><code>var database = blogContext.Client.GetDatabase("dbName");
  var collection = database.GetCollection&lt;Post&gt;("collectionName");
  var recentPosts = await blogContext.Posts.FindOne()
  </code></pre>
  
  <p>...</p>
  
  <p>However compiler throws an error that FindOne() method does not exists, which should I guess.</p>
  
  <p>Am I missing something?</p>
