// Stripe configuration

// Adding the .NET Identity User and Manager with database context
builder.Services.AddIdentity<IdentityUser, IdentityRole>().AddDefaultTokenProviders().AddEntityFrameworkStores<ApplicationDbContext>();

// Implement interface for data repository service
builder.Services.AddScoped<IUnitOfWork, UnitOfWork>();

// Create email service
builder.Services.AddSingleton<IEmailSender, EmailSender>();

// Adding Razor pages and Razor runtime compilation
builder.Services.AddRazorPages().AddRazorRuntimeCompilation();

// Creating service for Facebook social media authentication

// For https redirection and routing
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();

// Direction to use authentication and authorization (order important)
app.UseAuthentication(); ;
app.UseAuthorization();
app.UseSession();

// Adding Razor Page support
app.MapRazorPages();

// Specifying the application default route
app.MapControllerRoute(
    name: "default",
    pattern: "{area=Customer}/{controller=Home}/{action=Landing}/{id?}");

// Run the application 
app.Run();
