Question

I\'m trying to use Include extension on IQueryable set, but I have the following issue:

Answer 1

If you deploy directly to your repository, you can use Include(), as per example code below:

public IQueryable FindAll()
{
     var retRepository = from colaborador in All()
                            .Include(x => x.Cliente)
                            select colaborador;

     return retRepository;
}
