[英]EF7 UWP SQLite .Include() method
Want use Entity Framework 7 (Entity Framework Core) with SQLite in Universal Windows Application. 想要在通用Windows应用程序中将Entity Framework 7(Entity Framework Core)与SQLite一起使用。
Can`t find .Include(x => x.SomeNvaigationProperty) 找不到.include(x => x.SomeNvaigationProperty)
.Include() doesn't appear in intellisense .include()不会出现在智能感知中
.Include() in System.Data.Entity System.Data.Entity中的.include()
System.Data.Entity not available in UWP System.Data.Entity在UWP中不可用
What use in UWP (as .Include())? 在UWP中(如.Include())有什么用?
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();
在Entity Framework 7中, Include()放置了Microsoft.EntityFrameworkCore
You are adding wrong namespace using System.Linq
for .Include()
. 您正在using System.Linq
for .Include()
添加错误的名称空间。 You need to add using System.Data.Entity
then you will get .Include()
您需要using System.Data.Entity
添加,然后您将获得.Include()
