Using the MongoDB C# v2 Driver

Storing Files with GridFS
Recently in the 2. 2 version of the C# MongoDB driver, storing files and accessing files with GridFS has been overhauled as well. In this module we'll take a look at these changes and how to use the new APIs to access GridFS, and of course, you'll have access to both asynchronous APIs to GridFS and then new synchronous operations that match the new asynchronous operations. One of the notable changes is that GridFS has been split out into its own package and when we updated to the new MongoDB 2. 0 series of the driver, while we still have the Legacy driver and the new packages for the driver-driver core and BSON packages, we don't have the new GridFS API; we'll have to install that explicitly. We'll do that first. Then in this module we'll take a look at how to upload an image using the new APIs. We'll also talk about where you store content types now. There has been a change with regard to storing metadata for files. Then we'll take a look at how we can download an image in our rental application. We'll take a look at how we can delete files or delete images associated with our rentals, and then last, we'll wrap up by removing the Legacy driver, because at this point we'll now have updated all the code in this example application to use the new 2 series of the driver, so we'll go ahead and remove the Legacy driver.
