定义metadataAddress属性时未调用中间件

Question

我正在配置一个asp.net mvc app（或依赖方）来使用thinktecture身份服务器。 Identity Server已在本地启动并运行，我可以从其端点检索元数据。

以下是用于注册中间件的代码：

  app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions("localIdp")
            {
                AuthenticationType = "localIdp",                
                ClientId = "Welfare4Partners",
                MetadataAddress = "https://localhost:44333/core/.well-known/openid-configuration",
                //Configuration = new OpenIdConnectConfiguration
                //{
                //    AuthorizationEndpoint = "https://localhost:44333/core/connect/authorize",
                //    JwksUri = "https://localhost:44333/core/.well-known/jwks",
                //    TokenEndpoint = "https://localhost:44333/core/connect/token",
                //    UserInfoEndpoint = "https://localhost:44333/core/connect/userinfo",
                //    Issuer = "https://localhost:44333/core",
                //    EndSessionEndpoint = "https://localhost:44333/core/connect/endsession",
                //},                
                Notifications = new OpenIdConnectAuthenticationNotifications
                {
                    AuthorizationCodeReceived = (context) =>
                    {
                        return Task.FromResult(context);
                    },
                    SecurityTokenReceived = (context) =>
                    {
                        return Task.FromResult(context);
                    },
                    SecurityTokenValidated = (context) =>
                    {
                        return Task.FromResult(context);
                    },
                    AuthenticationFailed = (context) =>
                    {
                        context.HandleResponse();
                        context.OwinContext.Authentication.SignOut(CookieAuthenticationDefaults.AuthenticationType, context.Options.AuthenticationType);
                        context.SkipToNextMiddleware();
                        return Task.FromResult(context);
                    },
                    MessageReceived = (context) =>
                    {
                        return Task.FromResult(context);
                    },
                    RedirectToIdentityProvider = (context) =>
                    {
                        return Task.FromResult(context);
                    }
                },

                Authority = "https://localhost:44333",
                RedirectUri = AppSettings.PostLoginRedirectUri,                
                ResponseType = OpenIdConnectResponseTypes.IdToken,
                Scope = "openid",
                SignInAsAuthenticationType = CookieAuthenticationDefaults.AuthenticationType                
            });

正如您所看到的，一旦我设置了MetadataAddress支持，我就评论了Configuration属性。

我在Action中使用以下代码行调用中间件：

var authProperties = new AuthenticationProperties { RedirectUri = AppSettings.PostLoginRedirectUri, IsPersistent = false, };                
                OwinContext.Authentication.Challenge(authProperties, authenticationType);

我已经验证了authenticationType的值，它包含＆＃34; localIdp＆＃34;。在致电挑战后没有任何反应。奇怪的是，如果我评论metadataAddress并取消注释Configuration属性，则会调用中间件。

有没有办法调试OWIN请求以检查代码中的错误？
