By enabling Network Simulation and selecting a network speed, you can test various cellular data networks as well as Wi-Fi or scenarios where no networks are available.
Particularly interesting are the Signal Strength options, which affect the packet loss rate and network latency.
The good news is that you can upgrade such apps to Windows Phone 8 by right-clicking the Windows Phone 7.1 project in Visual Studio 2012 and selecting Upgrade to Windows Phone 8.
You’ll receive a prompt that cautions you that this upgrade can’t be undone and doesn’t update any referenced projects.
Because the Windows Phone XAML and XNA app template targets Windows Phone OS 7.1, you can still test your app on a Windows Phone 8 emulator.
Hello, in my project I enabled "Reduce xap size by using application library caching", but when I updated from sl4 to sl5, the sl4 libraries were cached by the browser, so, to avoid clear cache manually and update to the sl5 libraries in my users's browsers, I found a work around: -Unzip the file -Edit the App -In the Deployment.I have a Lumia 532 which has been upgraded to Windows 10.Gestures and Touch shows up in the list of apps needing updating.
