如何使用 IdentityServer4.AspNetIdentity 解决网页问题

Question

当我使用 IdentityServer4.AspNetIdentity 时。我使用个人用户设置使用 Visual Studio 2019 创建我的项目。它无法使用代码 500 打开我的网站

我用谷歌搜索了，但没有结果

我在 Startup.cs 中的代码：

 services.AddDbContext<ApplicationDbContext>(options =>
                options.UseInMemoryDatabase("AuthDb"));

services.AddIdentity<SimpleUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

services.AddIdentityServer()
    .AddDeveloperSigningCredential()
    .AddInMemoryPersistedGrants()
                    .AddInMemoryIdentityResources(Resources.GetIdentityResources())
    .AddInMemoryApiResources(Resources.GetApiResources())
    .AddInMemoryClients(Clients.Get())
    .AddAspNetIdentity<SimpleUser>()
    .AddDeveloperSigningCredential();

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

错误代码：

确保在 Views\Shared_LoginPartial.cshtml 中是

@inject SignInManager<SimpleUser> SignInManager
@inject UserManager<SimpleUser> UserManager

而不是

@inject SignInManager<IdentityUser> SignInManager
@inject UserManager<IdentityUser> UserManager
