Microsoft states:

"We want to make it as easy as possible to get started with Windows Bridge for iOS. In the coming weeks, we'll be launching a web tool that will automatically analyze your app for compatibility with the bridge and give you results right in your browser. You'll be able to see exactly how much work you'll have to do to bring your app to Windows, along with suggestions, tips and workarounds for any libraries you're using that the bridge doesn't support yet."
