HTML5 & JS in Windows Phone 8
• WP8 has only a subset of WinRT
• Does not support native HTML5 & JS apps
• You can have a browser control in your app to run web
content – that’s it!
• No WinJS to assist you
• No access to platform APIs
• In effect it is just a mini web page within the application
• All this was already possible in WP7.x
