[ASP.NET 5] Lazy DBContext initialization with Entity Framework 7

I will show you how to do lazy db context initialization with Entity Framework 7. The idea is simple, we need an easy way to get database context in a request. If db context was used in the request we should call SaveChanges method and dispose used context if not we shouldn't do anything. For "client", code should look like this: public class SomeRepository { private readonly IDbContext _db; public SomeRepository(IDbContext db) { _db = db; } public void Add(Item item) { _db.Current.Items.Add(ite...

I got this error after installing Visual Studio 2015 CTP 6 with Windows Phone 8.1 emulator. Sometimes  you can get this error if you turned off VTx or AMDv in bios. So, first things to do is: make sure that Virtualization is enabled in bios. Next - turn off Hyper-V. After installing Visual Studio with emulator it automatically turn Hyper-V on. And, apparently, Virtual Box cannot work together with Hyper-V. Run cmd.exe as administrator Execute command dism /online /disable-feature /featurename:Mi...

Идея заработка в интернете. Выводы

Чуть больше года назад я писал о идеи заработка в интернете. С момента начала у меня завелось 5 сайтов с контентом который я копировал с других сайтов (где это разрешено правилами и лицензией).

Результаты первого дня

Вчера я написал о начале маленького проекта по привлечению средств на помощь нашей армии, и уже сегодня видны результаты: 17$ за один день, это 340 грн по текущему курсу привата. И это в выходной день! Обычно в выходной день у меня было не больше 2$! (в будние дни ~10$) НО! Не нужно клацать на рекламу (ну только если она вам интересна)! Так как Google может заблокировать аккаунт если увидит подозрительную активность (а сегодня она была таковой) Наша цель сделать сайты популярнее для поисковиков,...
