title: ASP.Net Core using MongoDB.Driver.Builder driver
body: <p>I've a Web Api project where I am trying to use Query Object from the MongoDB.Driver.Builder library, but I can't find this library.
  I have installed MongoDB.Driver 2.4.0
  My Web Api Project is ASPNetCore 2.0.0</p>
  
  <p>There is a similar question here at Stackoverflow, though there is no solution only suggestion of using linq instead.
  Please refer to this link: <a href="https://stackoverflow.com/questions/48554622/unable-to-get-query-class-in-mongodb-driver">Unable to get Query class in MongoDb.Driver</a></p>
  
  <p>Which approach is more recommended and why can't I find this library?
  Thank you</p>
