Aunthendicate user and redirect to page using ADFS and WsFederation in .Net Core

Hi All,

I am facing some issues in authenticating user and page redirection using ADFS and WsFederation in (ConfigureService method) .net core application.

private void ConfigureAuth(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options =>
{
options.CheckConsentNeeded = context => false;
options.MinimumSameSitePolicy = SameSiteMode.None;
options.Secure = CookieSecurePolicy.SameAsRequest;
});

services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = WsFederationDefaults.AuthenticationScheme;
})
.AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
options =>
{
options.Cookie.Name = ".AspNet.SharedCookie";
options.Cookie.SecurePolicy = CookieSecurePolicy.SameAsRequest;
options.Cookie.SameSite = SameSiteMode.None;
})
.AddWsFederation(options =>
{
options.MetadataAddress =
$"https://login.microsoftonline.com/{aadTenant}/federationmetadata/2007-06/federationmetadata.xml";
options.Wtrealm = wTrealm;
options.Wreply = "http://localhost:61213/";
options.RequireHttpsMetadata = false;
});

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}

app.UseHttpsRedirection();

if (env.IsProduction())
{
app.UseStaticFiles();
app.UseSpaStaticFiles();
}

app.Use(async (context, next) =>
{
if (!context.User.Identity.IsAuthenticated)
{
await context.ChallengeAsync(WsFederationDefaults.AuthenticationScheme);
}
else
{
await next();
}
});

app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action=Index}/{id?}");
});

app.UseSpa(spa =>
{
// To learn more about options for serving an Angular SPA from ASP.NET Core,
// see https://go.microsoft.com/fwlink/?linkid=864501

spa.Options.SourcePath = "ClientApp";

if (env.IsDevelopment())
{
spa.UseAngularCliServer(npmScript: "start");
}
});

app.UseCookiePolicy();
app.UseAuthentication();
}

this always sending back me to the localhost://signin-wsfed .net core 500 error

Please help me to get rid the issue am facing in it and do the needful.

Thanks in advance

Looking forward to hearing from anybody ..
