1-UI，登陆界面布局
PS:使用的是metronic 框架，没有用过的可以自行百度。
1.1 metronic 放在wwwroot文件夹下面
1.2 metronic 中的 open sans 使用的是 谷歌的DNS，所以我们需要自己下载本地资源（使用nuget管理器下载，也可以用nuget控制台）。
1.3 创建Account控制器和视图 ，由于现在不支持在controller中直接右击生成视图文件，因此我们需要自己在Views文件下创建Account文件夹和Login.cshtml文件。
1.3.1 在Account 中创建布局页面Layout.cshtml

2.3 GR.Data中创建DependencyRegister依赖注册类（从Startup中分解出来）
之后只要是在Data中添加的类需要依赖注入，都是在该类中添加
1 using System; 2 using GR.Core.Data; 3 using GR.Data.Repository; 4 using Microsoft.EntityFrameworkCore; 5 using Microsoft.Extensions.DependencyInjection; 6 7 namespace GR.Data 8 { 9 public class DependencyRegister 10 { 11 public static void ConfigureServices(IServiceCollection services) 12 { 13 services.AddDbContext<GRDbContext>(ServiceLifetime.Singleton); 14 services.AddScoped(typeof(IRepository<>), typeof(EfRepository<>)); 15 } 16 } 17 }
2.3 GR.Servies中创建AccountService类，创建DTO实体模型，以及DependencyRegister依赖注册类
2.4 在gr.web中的startup添加依赖注册
3-结束
这样子登陆功能就完成了，其他的数据验证和.NET FRAMEWORK的一样
