I'm not sure if this has been answered yet, I looked at a couple of questions but I don't think they were quite what I was after. Let's say I have 3 tables: <pre><code>Restaurant 1.....M MenuCategory 1.....M MenuItem </code></pre> I have a L2E query that looks something like this: <pre><code>Restaurant = context.Restaurant .Include(r => r.MenuCategory) .FirstOrDefault(r => r.RestaurantId == resaurantId); </code></pre> Which works to some extent, but it only pre-loads the menu categories. As a work around I am able to iterate around each category and call .Load() on them, but this will involve hitting a lot more that in theory I should need to. What I really want to be able to do is something like: <pre><code>Restaurant = context.Restaurant .Include(r => r.MenuCategory) .Include(r => r.MenuCategory.MenuItems) .FirstOrDefault(r => r.RestaurantId == resaurantId); </code></pre> But clearly this isn't available as r.MenuCategory is an enumerable ANSWER 1: context.Restaurant.Include("MenuCategory.MenuItems"); <ul> <li>This works, but it is not strongly typed. I wonder if anyone is able to come up with a second answer that is strongly typed (I may move this to another question as this has been answered, and answered well.</li> </ul> I have moved this to another question as I felt it was unfair to take away from an answer that is perfect and works exactly as it should: <a href="https://stackoverflow.com/questions/1663783/entity-framework-include-in-sub-query-part-2">Entity Framework - Include in sub query? - Part 2</a>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
