How to include() nested child entity in linq

Question

How do I include a child of a child entitiy?

Ie, Jobs have Quotes which have QuoteItems

var job = db.Jobs
            .Where(x => x.JobID == id)
          


        

Answer 1

The method in the accepted answer doesn't work in .NET Core.

For anyone using .NET Core, while the magic string way does work, the cleaner way to do it would be ThenInclude:

var job = db.Jobs
        .Where(x => x.JobID == id)
        .Include(x => x.Quotes)
        .ThenInclude(x => x.QuoteItems)
        .SingleOrDefault();
