Support "Include" when using stored procedure in FromSql

Suppose we have a DTO:

public class Person
{
    public string FirstName { get; set; }
    public int Id { get; set; }
    public string LastName { get; set; }
    public Pet Pet { get; set; }
    public int PetId { get; set; }
}

public class Pet
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Currently running the code below throws “The Include operation is not supported when calling a stored procedure.”

db.Set<Person>().Include(p => p.Pet).FromSql("[dbo].[GetPersonsWithPets] @sortby = {0}", sortBy)

whereas if you use "SELECT Person.*, Pet.Name FROM Person INNER JOIN Pet on Person.PetId = Pet.Id", it works.

Can we get the same support for stored procedures? If they both return the same set of columns, it shouldn’t be an issue, should it?

Assuming you have two stored procedures with the same filter criteria:

db.Set<Pets>().FromSql("[dbo].[GetPetsForPersons] @lastName = {0}", lastName).Load();
var persons = db.Set<Person>().FromSql("[dbo].[GetPersons] @lastName = {0}", lastName);

when iterating over persons you will see that the references on each person point to the right pets.

BTW, with SQL Server you should be able to write queries against Table-Valued Functions as well.

But fundamentally you cannot do this with a single query.

EF will automatically wire up the references between entities that have been queried for
