title: How do I perform explain in current mongodb c# driver version?
body: <p>I'm just starting with MongoDb driver and I've found multiple posts on Stackoverflow, that say just add <code>.Explain()</code> to your IQueryable and it will do the magic. Problem is, that my IDE does not suggest such method.</p>
  
  <p>I've started digging and I see in master branch of MongoDb driver, that Explain extension method is in LinqExtensionMethods class, which itself is in MongoDB.Driver.Legacy, which is not referenced from the current driver?</p>
  
  <p>So what is the approach with current driver?</p>
