Project Description
GUI to enable Loopback Exemptions for Windows 8 Modern UI Apps

By default, Windows 8 Modern UI Applications are forbidden to send network traffic to the local Computer. In order to debug Apps with a tool, we need to enable Loopback capabilities for those Apps.
This tool enables the management of the Apps that can connect to the local Computer.
