You can apply on multiple tables and at multiple levels etc. The Include is a Eager Loading function, that tells Entity Framework that you want it to include data from other tables. The Include syntax can also be in string. Like this: db.Courses .Include("Module.Chapter") .Include("Lab") .Single(x => x.Id == id); But the samples in LinqPad explains this better. In Entity Framework core, things have changed drastically in this area. A query like _db.SampleEntity.Include(s => s.NavProp1).Select(s => new { s }) will now include NavProp1 in the end result. EF-core is smarter in looking for "Includable" entities in the end result.

Detta sker även I en och samma utvecklingsmiljö (IDE) som In Entity Framework, the Include method loads the related objects to include in the query results. It can be used to retrieve some information from the database and also want to include related entities. We have a simple model which contains two entities. Include (IQueryable, Expression>) 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). The best way to avoid the select N+1 problem in Entity Framework is to use the Include method.

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.

Eagerly Loading. 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.

The navigation property to be included is specified starting with the type of entity being queried (TEntity). The best way to avoid the select N+1 problem in Entity Framework is to use the Include method. It will create one query with needed data using SQL JOIN clause which is more efficient as compared to the previous one. Let's update our query by using the Include method.

Entity Framework Classic EF Classic 2013-10-07 · But it appears this will only be the case if queries exclude the use of "include". In my opinion this isn't much of an improvement because I think the majority of queries do use "include". But I'm pretty sure the EF team know that and hence I'm pretty sure they would have allowed for it in their solution. So my thought is that I've missed EF Core使用Include和join 在EF中表连接常用的有Join()和Include(),两者都可以实现两张表的连接，但又有所不同。例如有个唱片表Album（AlbumId,Name,CreateDate,GenreId），表中含外键GenreId连接流派表Genre(GenreId,Name)。每个唱片归属唯一一个流派，一个流派可以对应多个唱片。 The Entity Framework Core (EF) extension method Include provides us the ability to load additional data besides the entities we are querying for.
