搭建完整的 .Net Identity UI 源后，身份/帐户/管理页面的布局被破坏

Question

我正在遵循这些指南：

1. 未经现有授权将 Scaffold Identity 添加到 MVC 项目中
2. 创建完整的 Identity UI 源

遵循第一个指南后，我得到了我对“身份/帐户/管理”页面的期望：

然而，在遵循第二个指南后，布局被破坏了。侧面菜单丢失。该应用程序不再找到Areas/Identity/Pages/Account/Manage/_Layout.cshtml，我不明白为什么。

这是 git diff。

namespace WebIdentity.Areas.Identity
{
    public class IdentityHostingStartup : IHostingStartup
    {
        public void Configure(IWebHostBuilder builder)
        {
            builder.ConfigureServices((context, services) => {
                services.AddDbContext<IdentityDbContext>(options =>
                    options.UseSqlServer(
                        context.Configuration.GetConnectionString("IdentityDbContextConnection")));
 
-                services.AddDefaultIdentity<User>(options => options.SignIn.RequireConfirmedAccount = true)
-                    .AddEntityFrameworkStores<IdentityDbContext>();
+                services
+                    .AddIdentity<User, IdentityRole>(options => options.SignIn.RequireConfirmedAccount = true)
+                    .AddEntityFrameworkStores<IdentityDbContext>()
+                    .AddDefaultTokenProviders();
+
+                services
+                    .AddMvc()
+                    .AddRazorPagesOptions(options =>
+                    {
+                        options.Conventions.AuthorizeAreaFolder("Identity", "/Account/Manage");
+                        options.Conventions.AuthorizeAreaPage("Identity", "/Account/Logout");
+                    });
+
+                services.ConfigureApplicationCookie(options =>
+                {
+                    options.LoginPath = $"/Identity/Account/Login";
+                    options.LogoutPath = $"/Identity/Account/Logout";
+                    options.AccessDeniedPath = $"/Identity/Account/AccessDenied";
+                });
+
+                services.AddSingleton<IEmailSender, EmailSender>();
             });
         }
     }

只需在 Areas/Identity/Pages/Account/Manage 文件夹中添加 _ViewStart.cshtml 即可：

@{
   ViewData["ParentLayout"] = Layout;
   Layout = "_Layout.cshtml";
}
