Join Michael Sullivan for an in-depth discussion in this video Using LINQ to Entities, part of Learning ASP.NET.
…Having seen a lot of autogenerated database access code at this…point, you might be saying to yourself, well the scaffolding stuff…is handy, but how can I query my database for very…specific things, when I need to customize a little bit more?…We'll take a look at a few different ways to do that using LINQ to Entities.…So, we're going to continue with our…database first solution from the last video.…And for a simple example of something a little less…generic, let's add a new action method in tour controller.…
This new method will return a view that will list…all the tours that are of the highest difficulty rating.…Which is called Difficult.…And we're going to call the action method Difficult also.…We might start by copying the code in the Index method to get a base set of tours.…By the way, the use of the Include method here insures…that the related rating record is loaded along with the tour record.…This is an example of eager loading.…Since we're loading the rating details right…away before we even need to use them.…
