Debug Windows 10 Mobile Client
Frontend debugging of a client for Windows is probably the most accessible of the platforms.
When running the client, simply press the F12-button on your keyboard to open the dev console.
Pre-requisite: It must be an un-signed version of the application. If it was built in Phonegap using a signing key, a separate version that is built without the signing key is required. You can also debug in Visual Studio if you are building your app there.
