I have a already existing app for windows phone 8 but now I want to make a universal app for the same so that it can run on both windows phone and windows 8. I read about this on internet a lot but still I am confused that if a make a universal windows app will it be able to run on windows phone 8 and windows 8 as the most of the tutorials are confusing as they talk only about windows phone 8.1 and windows 8.1. Can anyone please help me on this whether this is possible or not ?
No. Universal app's is a new feature of Windows 8.1 and Windows Phone 8.1
They don't work on Windows 8 and Windows Phone 8.
No, Universal app for windows phone 8.1 and windows 8.1
There are Universal Apps for Windows 10 and Windows 8.1 but they are not compatible.
For further information: Run Windows 10 Universal Apps on Windows 8.1

I created an app with Visual Studio 2015 in this way : new Project -> Visual C# -> Windows -> Windows 8 -> Windows Phone.
My question is , is this app compatible with windows phone 7? I read something that the WinRT can make this happen, but I am not sure.
I tested the app on an Samsung device with Windows Phone 8.1 and it worked perfectly, can I assume that it works on Windows Phone 8 the same?
What about Windows 10 mobile? Is a Windows Phone 8.1 app installable on a device running on Windows 10 mobile?
I read the Wikipedia article about Windows Phone 8, but I did'nt get the information I was looking for.
Your app will work on Windows Phone 8/8.1 and Windows 10 Mobile.
It will not work on Windows Phone 7 devices.
My advice is to check better how it works on Windows 10 mobile - you might have surprises where the UI is slighlty different or some controls won't work as expected.
We had built an app using windows phone runtime 8.1, as you all know during build we get a .appx as output, but this .appx is not deployable on windows phone 8, as some of our customers still want to continue using windows phone 8, we are trying to port our windows phone runtime app to windows phone silverlight, but the question is can the existing users who are using the windows phone runtime app upgrade their app from windows phone 8.1 runtime to windows phone 8.1 silverlight ? assume that we only need to side load the app, we are not going to submit it to store.
So I am coming from Windows Phone Silverlight into the new Windows Phone runtime apps and Universal apps. I am attempting to build my first app after doing several of the tutorials from channel9. My question is, and maybe I am not googling this correctly, but how might I launch the built in apps in Windows 8 similar to Windows Phone 8 runtime? I've already built a sample using the runtime following http://msdn.microsoft.com/en-us/library/windows/apps/xaml/dn741261.aspx but what are the Uri Schemes for built in apps in Windows 8?
Zune does not recognize Windows Phone 8 devices? I can't run my project with the "Windows Phone Device" debug configuration. My OS is Windows 7, so my SDK should be the 7th. I've read that I need Windows SDK 8 so I could run my project in my Windows Phone 8, but for that I need to have Windows 8 in my PC as well. Is there any way to avoid this, and run successfully my 7.1 version app, in my Windows 7 PC, with the 7th SDK installed on my Windows Phone 8 device?
Thank you and sorry for the bad english.
For testing your app on Windows Phone 8 device you need Windows 8 + Windows Phone 8 SDK, or Visual Studio 2013 with this SDK built in.
Or you can upload your app as 'beta app' to Windows Phone Store and test it there, but that's not ideal for debugging, only for the final app testing.
I am developing an application in Windows 8.1 Preview release using VS 2013. When i deploy the App package in the Windows 8 PC, it did not run. I have a small question that whether Windows 8.1 developed apps will run in Windows 8 PC. If it needs to run, any other specification suppose to be provided for the apps or PC ?
If you target 8.1 then the app will not run in windows 8. That is because the api of 8.1 is extended and the new features do not exist in windows 8. If you develop in windows 8.1 and you target windows 8. Then the apps will just work out of the box.
For example, windows 8.1 supports new controls. If you target 8.1 you can use those controls, but when you use windows 8, those controls do not exist and thus the application cant run.
