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.

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.
I am trying to run my application on the Windows Phone 8 emulator on my laptop running Windows 8.1. When I start the emulator, I get this message: The Windows Phone Emulator requires Hyper-V. Your PC is missing the following pre-requisites required to run Hyper-V: Windows 8 Professional (64-bit)
I am already paying Microsoft to publish Windows Phone apps, I already paid them for my phone, and for Surface which does have Windows 8 Pro. Is there any way to run the emulator on my development computer without paying them to upgrade to Windows 8 Pro? (or getting it by shadier methods)
I checked to see if Hyper-V was listed in Windows Features, and it was not.
You need Hyper-V to run Windows Phone 8 emulator images since they are exactly that - images. They are not emulators like Windows Phone 7 emulators and they are only available on SLAT supporting processors and in Windows 8 64-bit.
If you have Surface Pro, you can develop on it. I managed to do that. If you have the normal Surface (not the pro version), you cannot run your development environment on it.
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.
The short story is: I have my laptop that has a processor without Virtualization and Second Level Adress Translation capabilities that are required for running the new Windows Phone 8 SDK.
I can however use the windows phone 7.1 sdk, but for testing my apps i will use a windows phone 8 device.
Is it possible to deploy and test my apps on the connected WP8 device, altough i am using the 7.1 SDK that predates the WP8 os?
I don't think it's possible to deploy apps using WP7.1 SDK on WP8 devices, however, you can install the Visual Studio 2012 + Windows Phone 8 SDK (if you have Windows 8 x64) even when you don't have SLAT enabled CPU. The Windows Phone 8 SDK will work, only you won't be able to launch the WP8 emulator.
No you cannot, The .xap packing mechanism in Windows phone 7.1 and 8 are different so you cannot deploy this xap using deployment tool. But, if we are using windows 8 + wp8 dev tools you can debug the application that developed on 7.1. In future after the launch of wp 7.8 ms may provide a solution for this. for now there is no other alternative is available in front of you
