随着 NET 5 的正式发布，今晚我从 Net Core 3.1 迁移到 NET 5，一切似乎都很顺利，直到我尝试运行该应用程序，现在在 startup.cs 中的两个项目下发现了几条波浪线与 Microsoft Identity Web 平台相关联。这显然是一时的失败！在修复此问题之前，我将无法启动应用程序或登录 Azure AD。
将csproj文件修改为NET5后，我去nuget manager更新了所有的包。
我完全不知道从哪里开始处理这个问题:(
带有波浪线的 startup.cs 文件的屏幕截图：
csproj 文件：
带有更新包的 Nuget 管理器：
我注意到，自迁移以来，MS Identity Web 的 startup.cs 文件顶部的包引用现在显示为灰色：
startup.cs 文件中的代码：
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public TokenValidatedContext Context { get; set; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Added to original .net core template.
// ASP.NET Core apps access the HttpContext through the IHttpContextAccessor interface and
// its default implementation HttpContextAccessor. It's only necessary to use IHttpContextAccessor
// when you need access to the HttpContext inside a service.
// Example usage - we're using this to retrieve the details of the currrently logged in user in page model actions.
services.AddHttpContextAccessor();
// DO NOT DELETE (for now...)
// This 'Microsoft.AspNetCore.Authentication.AzureAD.UI' library was originally used for Azure Ad authentication
// before we implemented the newer Microsoft.Identity.Web and Microsoft.Identity.Web.UI NuGet packages.
// Note after implememting the newer library for authetication, we had to modify the _LoginPartial.cshtml file.
//services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
// .AddAzureAD(options => Configuration.Bind("AzureAd", options));

// Add services required for using options.

services.Configure<OpenIdConnectOptions>(OpenIdConnectDefaults.AuthenticationScheme, options =>

// Adding authorization policies that enforce authorization using Azure AD roles. Polices defined in seperate classes.
services.AddAuthorization(options =>

//options.AddPolicy(AuthorizationPolicies.AssignmentToUserReaderRoleRequired, policy => policy.RequireRole(AppRole.UserReaders));

// The AddAntiforgery() method configures anti-forgery service to pick the anti-forgery

services.AddAntiforgery(options => options.HeaderName = "MY-XSRF-TOKEN");
}
我只是不知道如何解决这个问题......
