Update June 1st: we have pushed the support end date to July 10, 2016.
We want to let you know that we will be ending Windows Phone support in the Appery.io platform on
May 15, 2016 July 10, 2016. The reason for this is very simple; very few Windows Phone apps are being built and deployed on the Appery.io platform; even Microsoft bets its future on the universal Windows 10 applications, and not on the Windows Phone (information regarding this topic can be found here, and here). The resources we used to support the Windows Phone will be redirected to add a more easy-to-use tooling for building enterprise iOS and Android apps, which is a good thing.
If you need to export a Windows Phone project source or build a binary, go to Export windows inside the App Builder:
You will be able to export the files until May 15, 2016.
