Another classic problem of Windows Phone emulator is that it does not respond as expected if we have the support for both the orientations (Portrait & Landscape) by mentioning
it still not changing in Emulator. What could be the reason, think?
It is because you have removed the On-Screen keyboard by pressing Ctrl+Page Up (I discussed this in my previous post), so you just need to get them back to the default mode by pressing ctrl+Page Down.
This behavior is not regular, if you are lucky your Emulator should work as is without this trick as well. This is what I found during my tryouts.
