I am new to Windows Phone Development Environment, looked around on SO but couldn’t find a clear answer to the question I have.
With Windows Phone SDK 8 publicly available, and new Windows Phones getting good reviews, one of our Clients is looking to launch their app on Windows Phone Platform as well (they already have it on iPhone). The app is pretty simple. Obviously Client would like their app to be compatible and available to as many as possible users/devices – WP7, WP7.5 and WP8.
Question is – what SDK version should I use to develop this app? Currently I have Windows 8 with 64-Bit, VS 2012 Express and Windows Phone SDK 8.0 already installed and ready to go for development. So if develop app using above tools, will it run on all the devices with WP 7,WP 7.5 and WP 8 on them?
What is a good approach to develop a brand new Windows Phone App that would run on WP 7,WP 7.5 and WP 8 Devices.
The complete answer is on this MSDN page:
Windows Phone versions
Basically you can create application targeting the WP7.5 platform and it will run on all current Windows Phone devices, or you can target only Windows Phone 8, then it will run only on new WP8 devices, but when targeting this newer platform, you can use broader set of APIs and features.
