When I try to start debugging my windows phone 8 app in Emulator WVGA 512MB
the following error message is showing
The Windows Phone Emulator wasn\'t
If you have a computer with a touch-screen and get this error, it can be because Hyper-V is trying to port over the touchscreen-fx to the virtual device.
This is (when found) easily corrected:
Shut down all attempt at launching virtual devices.
Go to: Hyper-V Manager->Hyper-V-settings->Physical GPU:s // Uncheck box "use this GPU with RemoteFX"
This worked for me (found here):
follow the following steps to solve this problem
1.go to network and sharing center
2.go to change adapter setting
3.go to v Ethernet (internal Ethernet port windows phone emulator internal switch)
4.right click it and enable it(if already enabled then disable and enable it again).
If you are loading the emulator for the first time, it behaves just like the phone (on first boot) where it will install the initial set of apps and configure them. Which is why the first start will take a long time. You can actually open Hyper-V manager and connect to the VM you had selected at the time of initiating debug - to see the actual progress of what is happening. Hope this helps.
No magic needed. Just reboot your development machine after installing Windows Phone SDK.
You can disable Hyper-V
from Program and Features
and reboot your machine twice. Everything will be default. Enable Hyper-V
and reboot twice and everything should be working again.
what your describing is usually due to a Firewall of a third party Anti-virus.
If your using Symantec follow this procedure https://stackoverflow.com/a/26326528/4446346
If your using Windows Firewall follow this procedure https://stackoverflow.com/a/27685167/4446346
and If you'r using AVG do the following procedure:
One more thing you must do is go to the "Windows Phone Emulator Internal Switch" and uncheck "AVG network filter driver"
open Network and Sharing Center-->Change Adapter Settings-->Properties
Uncheck "AVG network filter driver"
