Allow localhost loopback capability in UWP apps deployed to the Microsoft Store
UWP apps currently are not able to access localhost on the same machine that the app is running on. This docs page describes the limitation: https://docs.microsoft.com/en-us/windows/uwp/debug-test-perf/deploying-and-debugging-uwp-apps#debugging-options
When debugging, Visual Studio is capable of adding an exemption for the UWP app, but obviously, this exemption does not apply once the app has been published to the store.
Please add a new capability to UWP apps that allows for them to access localhost.
