EF7 UWP SQLite .Include() method

Question

Want use Entity Framework 7 (Entity Framework Core) with SQLite in Universal Windows Application.

Can`t find .Include(x => x.SomeNvaigationProperty)

.Include() doesn't appear in intellisense

.Include() in System.Data.Entity

System.Data.Entity not available in UWP

What use in UWP (as .Include())?

public class Parent
{
   public Guid Id { get; set; }
   public List<Child> Childs { get; set; }
}

public class Child
{
   public Guid Id { get; set; }
   public Guid ParentId { get; set; }
   public Parent Parent { get; set; }
}

dbContext.Parent.Include(x => x.Childs).ToList();
dbContext.Childs.Include(x => x.Parent).ToList();

Answer 1

在Entity Framework 7中， Include（）放置了Microsoft.EntityFrameworkCore

Answer 2

You are adding wrong namespace using System.Linq for .Include() . You need to add using System.Data.Entity then you will get .Include()
