Is anyone able to connect to MongoDB using the new mongodb .net 2.0 client?

Question

I installed MongoDB.Driver 2.0 from nuget published 4/2/2015. I also installed MondgoDB via chocolatey version 2.4.7. I created a test app in VS2013, as follows:

var client = new MongoClient();
var database = client.GetDatabase("foo");
var foo = database.GetCollection<BsonDocument>("bar");

From what I have read in the docs, this should be sufficient to connect to the server and create the database. When I check the mongodb via robomongo, I dont see that the database "foo" has been created.

I tried running mongodb via windows server and via command line (admin mode), with no results. I have disabled my firewall just in case that was an issue; still nothing. I have to say that as my first foray into MongoDB I would have expected this to just work.

What am I missing?

... and create the database

there is no such operation in mongodb, databases are created when you attempt to insert data into one

You're not asking the driver to actually do anything. All operations are lazy. To have the driver connect and insert a document, thereby creating both the database and the collection, do something like this:

var foo = database.GetCollection<Customer>("customer");
foo.InsertOneAsync(new Customer { Name = "John Doe" }).Wait();

where Customer is a class, e.g.

public class Customer { 
  public ObjectId Id { get; set; }
  public string Name { get; set; }
}

Of course, you can also work with BsonDocuments, but that seems unnecessarily cumbersome.
