How does Entity Framework work with recursive hierarchies? Include() seems not to work with it

Question

I have an Item. Item has a Category.

Category has ID, Name, Parent

Answer 1

My suggestion would be

var query = CreateQuery()
    .Where(entity => entity.Id == Id)
    .Include(entity => entity.Parent);
var result = await FindAsync(query);

return result.FirstOrDefault();

and it means it will load single entity and all this entity.Parent entities recursive.

entity is same as entity.Parent
