How can I find by ID in Mongo C# Driver 2.2.3
<p>My source code is not working </p>

<pre><code>public async Task&lt;ActionResult&gt; AdjustPrice(string id)
{
    var filter = new BsonDocument("_id",id);                     
    return View(await Context.Rentals().Find(filter).FirstOrDefaultAsync());
}
</code></pre>
