As this question is the top search result for "Entity Framework Include not working" I'm just going to mention a couple of other possibilities even though neither are relevant for @Dismissile's original post. Case Sensitivity. SQL Server (and possibly other database platforms) often work in a case-insensitive manner.

Using Include with Eager Loading Entity Framework also supports another type of fetching data – eager loading. This one is safer for your performance (if you have no idea what you’re doing) but might cause exceptions in a runtime. Now when you execute the above example, you will see that it will retrieve the customer with id equal to 1 and will include all the invoices. That is because the where clause is just acting on the customer but not on Invoices. EF: Include with where clause Entity Framework Classic Include Description.

So reiterating what @mikes-gh wrote months ago: Don't underestimate the value of filtered include.

Include (IQueryable, String) Specifies related entities to include in the query results. The navigation property to be included is specified starting with the type of entity being queried ( TEntity ). Further navigation properties to be included can be appended, separated by the '.' character.

In the previous pose we saw on how to join tables using the join keyword. Entity Framework core  It sounds like you actually have a many to many relationship.

In addition to this, it also provides the ThenInclude() extension method to load multiple levels of related entities. (EF 6 does not support the ThenInclude() method.) Include Explicit loading means that the related data is explicitly loaded from the database at a later time. Lazy loading means that the related data is transparently loaded from the database when the navigation property is accessed. Because the Include method returns the query object, you can call this method multiple times on an ObjectQuery to specify multiple paths for the query, as in the following example: // Create a SalesOrderHeader query with two query paths, // one that returns order items and a second that returns the // billing and shipping addresses for each order.

Eager loading is the process whereby a query for one type of entity also loads related entities as part of the query. Eager loading is achieved by use of the Include method. For example, the queries below will load blogs and all the posts related to each blog.

The only workaround is writing raw SQL but in many cases you need it for almost all of your queries, so that's not an option or else why use an ORM to begin with. So reiterating what @mikes-gh wrote months ago: Don't underestimate the value of filtered include. It was a top request in ef 6.

For years (quite literally 3 years) I’ve been waiting for filtering to be available on includes within Entity Framework, or more specifically, EF Core. Finally, the next preview should have this included. From the pull request, the additional operations to be specified inside Include/ThenInclude are:

Use the Load() method to load related entities explicitly. Consider the following example. I have several example in this website that include with a string the property when it’s a property inside a collection of my main entity. Here is one example: return DatabaseContext .SetOwnable() .Include(x => x.Sessions) .Include("Sessions.WorkoutSessionExercises") .Include("Sessions.WorkoutSessionExercises.Exercise") .Single(c => c.Id == id); 2014-07-25 When I wrote user interface for my TemperatureStation solution I faced some bad problems with Entity Framework Core when trying to query base type and get some navigation properties of derived types included. I was able to come out with some work-arounds that were far from being satisfying for me. Include for derived types in Entity Framework Core solves the problem.

Entity Framework fork with .NET Core support and must-haves built-in features. Entity Framework Classic EF Classic Disclaimer: I'm the owner of the project Entity Framework Plus. Our Library doesn't support Query Filter yet for .NET Core due to the N+1 queries issue. Under our hood for EF6, our library was only doing a simple projection. Include / ThenInclude methods support eager loading of the related data entities. They are not needed when you use projection ( Select ). Interestingly, all EF (Core) versions before EFC 2.0 were ignoring includes for projection type queries.
