What’s New in the MongoDB .NET 2.1 Driver

The 2.1 driver ships with a number of new features. The most notable are discussed below.

GridFS

CSHARP-1191 - GridFS support has been implemented.

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.

Eventing

CSHARP-1374 - An eventing API has been added allowing a user to subscribe to one or more events from the core driver for insight into server discovery, server selection, connection pooling, and commands.
