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 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.
