从2.2升级到3后，ASP.Net Core身份验证不起作用

Question

我在ASP.NET Core 2.2中有一个启用了身份验证的Web应用程序（类型MVC）（这是使用dotnet aspnet-codegenerator身份生成的）。一切都很好，直到那里。我必须将项目升级到ASP.Net Core 3.0，并且身份验证停止工作。 ¿有人可以帮我吗？

我认为我已经在documentation from Microsoft中提出了要点，但是我不知道出了什么问题。

项目参考：

<ItemGroup>        
<PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="3.0.0" />        
<PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0" />        
<PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.0.0" />        
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0" />        
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.0.0">
  <PrivateAssets>all</PrivateAssets>
  <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>        
<PackageReference Include="Microsoft.Extensions.Identity.Core" Version="3.0.0" />        
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.0.0" />        
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Utils" Version="3.0.0" />        
<PackageReference Include="RestSharp" Version="106.6.10" />
<PackageReference Include="Serilog" Version="2.9.0" />
<PackageReference Include="System.Linq.Queryable" Version="4.3.0" />

当我在VS中的调试中测试项目时，登录选项会导致： 本地主机/？area = Identity＆page =％2FAccount％2FLogin

在迁移之前，它导致： 本地主机/身份/帐户/登录

如果我手动加载它，则会显示错误404

               );
        });
    }

IdentityHostingStartup类 [程序集：HostingStartup（typeof（GLB.Wallet.Backoffice.Areas.Identity.IdentityHostingStartup）））

public class IdentityHostingStartup : IHostingStartup
{
    public void Configure(IWebHostBuilder builder)
    {
        builder.ConfigureServices((context, services) => {
            services.AddDbContext<IdentityDataContext>(options =>
                options.UseSqlServer(
                    context.Configuration.GetConnectionString("BackofficeConn")));

            services.AddDefaultIdentity<IdentityUser>()
                .AddEntityFrameworkStores<IdentityDataContext>();
        });
    }
}
