I am not getting where is the issue. Can someone please help me?

Answer 1

Uninstall your app, and then deploy it works for me.

Answer 2

Reboot Your Windows Phone.

Always works for me!

Answer 3

The most common reason for this issue is about your Hard Disk, check if you have enough free storage space and try running a chkdsk.

Otherwise can be your Emulator Configuration.
