Configuring session state

Open the Startup.cs file and add the following statements to the end of the
ConfigureServices method, after the call to the AddMvc method:
services.AddCaching();
services.AddSession(options =>
{
options.CookieName = ".Packt.QuizWebApp";
options.IdleTimeout = TimeSpan.FromMinutes(10);
});
Add the following statements to the end of the Configure method, before and
after the call to the UseMvc method, to use the session state and to populate the
sample questions:
app.UseSession(); // must be added before MVC
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
app.UseSampleQuestions(env.MapPath("")); // pass the path to the
wwwroot directory
