Entity Framework .Include() Navigation of another Navigation property

Question

I have an entity Test. It contains a Navaigation Property Question and Question contains a Navigation Property QuestionLocale.

var test = context.Tests
       .Include("Question")
       .FirstOrDefault();

works as expected. But how is it possible to include the QuestionLocale?

Answer 1

You can do it in a strongly typed way too

var test = context.Tests
                .Include(x => x.Question.Select(child => child.QuestionLocale))
                .FirstOrDefault()

Answer 2

Now there is ThenInclude see Microsoft Documentation, that solved it for me

var test = context.Tests.Include(x => x.Question).ThenInclude(q => q.QuestionLocale).FirstOrDefault();
