windows-phone-8

问题 I am new to Windows Phone 8 development. I have registered (unlocked) my phone in Windows Phone Developer registration. And I can see the phone in File Explorer. But when I launch MSVC 2013 Update 2 and open DirectX 3D shooting game sample , I can only see a plenty of emulators in dropbox and I don't see my phone. What could be wrong?

问题 I am writing an App with some reasonably sensitive data in it. At the moment is uses a forms based login page, username and password. I currently cache the username but not the password - forcing the user to type it in each time. One of my users has pointed out that if they already lock the phone with a PIN, it is not much less safe to cache the password as well. So, can you detect whether a WinPhone8 device is using a PIN on the lock screen? 回答1: Unfortunately there is currently no API

问题 Is it possible to get the WP8 emulator to access a ASP.NET Development debug server I run on my pc? WP8 Emulator runs inside Hyper-V and the debug server on my pc is therefore not accessible to the emulator, is it possible to do so it is? Only solution I can come up with is create a IIS server on my machine and debug that, but its much easier running development server. 回答1: The problem isn't really "how to access the development server from the emulator", but "how to access the development
