C# ASP.NET核心MVC-应用数据库迁移时未创建用户表,c#,asp.net-core,asp.net-core-mvc,sqlclient,C#,Asp.net Core,Asp.net Core Mvc,Sqlclient,我有一个Asp.net Core MVC项目，执行以下命令时，没有在数据库中创建用户表： Add-Migration migrationName Update-Database 它将更新模型链接到的表，但不会添加用户表。这是一个问题，因为我想使用ASP.NET核心MVC框架提供的登录功能，我认为这些表应该在应用迁移时自动填充数据库有人知道为什么在通过nugget package manager控制台更新数据库时不会自动发生这种情况吗？这是我从github得到的一个朋友的项目，我需要处理它，

我有一个Asp.net Core MVC项目，执行以下命令时，没有在数据库中创建用户表：

Add-Migration migrationName

Update-Database

它将更新模型链接到的表，但不会添加用户表。这是一个问题，因为我想使用ASP.NET核心MVC框架提供的登录功能，我认为这些表应该在应用迁移时自动填充数据库

有人知道为什么在通过nugget package manager控制台更新数据库时不会自动发生这种情况吗？这是我从github得到的一个朋友的项目，我需要处理它，我不确定要检查什么来确保他们正确配置了这个项目，以便自动创建用户表

如何配置项目以自动添加用户表

任何帮助都将不胜感激-我已经查看了以前的堆栈溢出答案，但大多数都过时了

编辑：数据库中的迁移表确实包含我应用于数据库的userTest迁移。这是在MVC项目中创建的迁移文件，如果有帮助的话：

using Microsoft.EntityFrameworkCore.Migrations;

namespace SEWebPage03.Migrations
{
    public partial class userTest : Migration
    {
        protected override void Up(MigrationBuilder migrationBuilder)
        {

        }

        protected override void Down(MigrationBuilder migrationBuilder)
        {

        }
    }
}

如果在创建项目时选择了

No Authentication

，则需要手动构建Identity Framework。
这可以完成…需要几个步骤

首先是修改

ApplicationDbContext.cs

更改此行

public class ApplicationDbContext: DbContext {}

对此

public class ApplicationDbContext: IdentityDbContext {}

您需要安装这些Nuget软件包。
Microsoft.AspNetCore.Identity.EntityFrameworkCore
Microsoft.AspNetCore.Identity.UI

下次更改启动。cs
在

ConfigureServices下
添加：

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<ApplicationDbContext>();

现在添加一个新的迁移

PM->添加迁移脚手架属性
PM->更新数据库
身份迁移
