second issue

InvalidOperationException: The default Identity UI layout requires a partial view '_LoginPartial' usually located at '/Pages/_LoginPartial' or at '/Views/Shared/_LoginPartial' to work. Based on your configuration we have looked at it in the following locations:

/Areas/Identity/Pages/Account/_LoginPartial.cshtml
    /Areas/Identity/Pages/_LoginPartial.cshtml
    /Areas/Identity/Pages/Shared/_LoginPartial.cshtml
    /Areas/Identity/Views/Shared/_LoginPartial.cshtml
    /Pages/Shared/_LoginPartial.cshtml
    /Views/Shared/_LoginPartial.cshtml.

my project configuration

    var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
var services = builder.Services;
services.AddDbContext<GasdwahedDbContext>(options =>

    options.UseSqlServer(

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())

app.UseHttpsRedirection();

app.UseRouting();

app.UseForwardedHeaders(new ForwardedHeadersOptions

    ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});

app.UseAuthentication();
app.UseAuthorization();

app.MapRazorPages();

app.MapControllerRoute(
    name: "MyArea",
    pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}");

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

Answer 1

Simply the provocative solution is :

1- right click on file which has problem.

2- choose properities.

3- change Build action to Content instead of none or anything else.
