I am using Visual Studio 2012 and Want to do Windows Phone Development on This Visual Studio so can anyone Suggest me Which WPF SDK Should I download , I download Windows Phone SDK 7.1 , but it is giving me an error and I can't install WPF 8 as it needs 64 bit OS and I don't have it, please suggest me some suitable configuration to work on 32 bit OS and 32 bit machine with Visual Studio 2012.
I don't want to install Windows Phone 8 SDK on my 32 bit machine I just want to know whether there is any solution exist by which I can develop apps in Windows Phone with Visual Studio 2012.
The possible solutions to develop for Windows Phone:
Conclusion: Get a 64bit machine :)
Note that while 7.1 apps will most likely run on later versions, they might not scale correctly to the new resolutions, have a few quirks and certainly you'll miss out on a lot of new features. If you start on a new app I'd recommend you to go for either 8.1 or even Windows 10 (depending if you want to support desktop-tablets and maybe even Xbox, HoloLens, ...).
Compare it to Android: if you start on a new app today, you won't create a 1.5 (Cupcake) / 1.6 (Donut) / 2.0 (Eclair) app. I guess you'd go for at least 4.1 (Jelly Bean) for new features and drop the 5% of users that use older versions.
