Только что обновлено до MVC 6 RC 1 и создано новое приложение MVC.MVC 6, HomeControler Index() называется дважды
Обнаружено, что метод действия индекса вызывается дважды.
Index() в HomeControler:
public string Index()
{
System.Diagnostics.Debug.WriteLine("############################");
return string.Empty;
}
Я удалил все от Startup.cs Настройки, за исключением маршрутизации по умолчанию.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
Глобальная компоновка удалена. _ViewStart.cshtml
@{
// Layout = "_Layout";
}
Выход в браузере пуст. Нет сценариев.

Найдено, что конструктор HomeControler вызывается дважды ???
public class HomeController : Controller
{
public HomeController()
{
System.Diagnostics.Debug.WriteLine("CCCCCCCCCCCCCCCCCCCCCC");
}
public string Index()
{
return string.Empty;
}

EDIT 2
Вероятно, проблема появляется только в режиме отладки:
public static class Counter
{
public static int CtrCalled { get; set; }
public static int IndexCalled { get; set; }
}
public class HomeController : Controller
{
public HomeController()
{
Counter.CtrCalled++;
}
public string Index()
{
Counter.IndexCalled++;
return $"Constructor called: {Counter.CtrCalled}, Index called: {Counter.IndexCalled}.";
}
}
выход Режим отладки: Constructor called: 2, Index called: 1.
режим отладки с отладочных точек: Constructor called: 2, Index called: 2.
релиз Режим вывода: Constructor called: 1, Index called: 1.
Ваш взгляд пуст? –
Да. Вид пуст. Однако я заметил, что проблема только в режиме отладки. –
Вы используете 'DependecyResolver'? –
