使用EF7配置级联删除 [英] Configuring cascade delete with EF7

问题描述

我正在尝试在ASP.NET vNext应用程序中使用EF7配置级联删除，但是我找不到如何做的方法。

I'm trying to configure a cascade delete using EF7 in a ASP.NET vNext application but I cannot find how to do it.

我正在重写 OnModelCreating ，我有以下代码：

I'm overriding OnModelCreating and I have this code:

  modelBuilder.Entity<Category>()
              .OneToMany<Category>( e => e.SubCategories )
              .ForeignKey( e => e.ParentCategoryId );

生成的迁移如下：

    migrationBuilder.AddForeignKey("Category", "FK_Category_Category_ParentCategoryId", new[] { "ParentCategoryId" }, "Category", new[] { "Id" }, cascadeDelete: false);

任何人都知道在哪个命名空间中定义了配置级联删除的扩展名吗？

Anyone know in what namespace the extensions to configure the cascade delete are defined?

谢谢！
