HTTP错误500.30-ASP.NET Core 2.2中的ANCM进程内启动失败错误

问题描述

我正在配置此应用程序确认帐户并在ASP.NET Core中恢复密码但我有一个错误:

I am configuring this applicationConfirming the account and recovering passwords in ASP.NET Corebut I have an error:

下面是我的配置:

[assembly: HostingStartup(typeof(Misioneros.Stella.Maris.Web.Areas.Identity.IdentityHostingStartup))]
namespace Misioneros.Stella.Maris.Web.Areas.Identity
{
    public class IdentityHostingStartup : IHostingStartup
    {
        public void Configure(IWebHostBuilder builder)
        {
            builder.ConfigureServices((context, services) => {
                services.AddDbContext<ApplicationDbContext>(options =>
                    options.UseSqlServer(
                        context.Configuration.GetConnectionString("DefaultConnection")));

                services.AddDefaultIdentity<IdentityUser>(config =>
                {
                    config.SignIn.RequireConfirmedEmail = true;
                })
                    .AddEntityFrameworkStores<ApplicationDbContext>();
            });
        }
    }
}

有什么问题吗?

推荐答案

我明白了原因.可能是您在应用程序中两次注册了Identity，如下所示:

I got the reason. May be you are registering Identity twice in your application as follows:

启动类的ConfigureServices方法之一:

services.AddDefaultIdentity<IdentityUser>()
                .AddDefaultUI(UIFramework.Bootstrap4)
                .AddEntityFrameworkStores<ApplicationDbContext>();

以及IdentityHostingStartup中的其他内容:

services.AddDefaultIdentity<IdentityUser>(config =>
                {
                    config.SignIn.RequireConfirmedEmail = true;
                }).AddEntityFrameworkStores<ApplicationDbContext>();

将Identity注册在一个位置，即使用ConfigureServices方法还是IdentityHostingStartup.

Register Identity just in one place i.e either in ConfigureServices method or in IdentityHostingStartup.

希望这会对您有所帮助.

Hope this will help you.
