Is AsQueryable method departed in new Mongodb C# driver 2.0rc?

Question

First of all I'm new to MongoDb. In MongoDb C# driver 1.9.x, i can take collections as queryable with AsQueryable method like this.

        var db = client.GetServer().GetDatabase("test");         var col = db.GetCollection("Video");         var qrlist = col.AsQueryable(); 

I installed new driver 2.0rc and while using it, i cannot use AsQueryable method because it is missing. Is it departed or is there another way to accomplish this? (I have already included MongoDB.Driver.Linq).

        var db = client.GetDatabase("test");         var col = db.GetCollection<Contact>("Contact"); //GetCollection without <T> is missing to.         var qrlist = col.AsQueryable(); // AsQueryable missing here. 

How can i get my entities as queryable in new driver, need help from MongoDb gurus. Thank you.

19 October update:

MongoDB 2.1 driver is out https://github.com/mongodb/mongo-csharp-driver/releases/tag/v2.1.0

It supports LINQ:

LINQ

CSHARP-935 LINQ support has been rewritten and now targets the aggregation framework. It is a more natural translation and enables many features of LINQ that were previously not able to be translated.

Simply use the new AsQueryable method to work with LINQ.

18 September update:

MongoDB 2.1 driver RC should support it. See https://jira.mongodb.org/browse/CSHARP-935

Finally 2.1 rc came out. Great work!

Old answer:

No, AsQueryable is unsupported: https://jira.mongodb.org/browse/CSHARP-935

And from the hourse's mouth: Craig Wilson on the google forum

Yes, there is currently no AsQueryable on the new api. You can track this feature here (https://jira.mongodb.org/browse/CSHARP-935). We simply didn't have enough time to get it completed and tested thoroughly. It is scheduled for 2.1 and is a priority for us. Until then, we have integrated expression tree functionality into the Find and Aggregate methods (and some of the write methods for filtering) such that you may not need a full LINQ implementation. For instance, see the sample test class here as an example: https://github.com/mongodb/mongo-csharp-driver/blob/master/src/MongoDB.Driver.Tests/Samples/AggregationSample.cs#L77
