                 var result = Builders<BsonDocument>.Filter.Where(x => x["_id"] != "");
            var registry = BsonSerializer.SerializerRegistry;
            var serializer = registry.GetSerializer<BsonDocument>();
            var mql = result.Render(serializer, registry, Linq.LinqProvider.V3);

      The above code triggers exception:

      MongoDB.Driver.Linq.ExpressionNotSupportedException: 'Expression not supported: (x.get_Item("_id") != ).'
