I have a universal app for Windows 8.1 and Phone 8.1 and am looking to make the jump to Windows 10.
Looking at the guides, I need to recreate the projects, but does this mean this new project will only work on Windows 10?
What is the strategy for this setup? Keep a Windows 8.1 version and a Windows 10 version? Or does the Windows 10 version work on 8.1?
You can't.
Windows 10 introduces several new API and also included old API's those work in Windows 8. but you just simply can't run Windows 10 app in Windows 8 environment.
if you look at this site: http://www.jayway.com/2015/06/16/do-windows-8-apps-run-on-windows-10/
he tells us that Win 8 app runs Win 10 but lack of some feature such as charm bar and splash screen.
of course this concerns many developer but in my honest opinion, you should just move on to developing app for windows 10. everyone will upgrade, eventually.
there's so many advantages for developing win 10 app, one of them is your app will run on broader device and market.

I need to create a Windows Phone 8.0 as well as Windows Phone 8.1 app from already developed IBM Worklight(6.1) Project. Is there any document that elucidates end to end solution to do that? Also could you please elucidate tools/plugins required?
To your existing MFP/Worklight project, you can add the Windows Phone environment. This will generate the Visual Studio project for Windows Phone. The same app can be run on Windows Phone 8.0 and 8.1.
The following getting started modules give you an overview of whats needed to develop a Windows Phone app.

is it possible to develop an app for windows 8 and it will run on windows 8.1 normally? what about the validation in the store? and its visibility in the store for users who have windows 8.1 on their pcs?
why visual studio 2013 professional version is supported by windows 8 and not visual studio 2013 express edition for windows?
if we developp a library in windows phone 8, could we reuse it in Windows 8.1 application? (specifically its validation in the store?)
thx for ur answers
Will a Win8 app run on Win8.1?
Check this question here on SO: Migration Windows Store App based on 8.1. does it has backward compatibility with 8?
Basically, the answer is YES. But not the other way around. Windows 8.1 apps will not work on Windows 8. So the visibility in the store depends on the targeted version of the app and the version that is running. Win 8.1 users will see both and Win 8 users only see Win 8 apps.
VS2013 Express on Windows 8.1 only?
Depends on the type of VS you want. Check the Visual Studio Express page and decide which version you want. For example Express 2013 for Windows will only work on Windows 8.1, while Express 2013 for Windows Desktop will also work on Windows 8.
Windows Phone 8 to Windows 8?
Channel9 Always had interesting posts about development and for this case too. Check the page Building Apps for Both Windows 8 and Windows Phone 8 Jump Start for more information about developing for both platforms.
Hope this helps! :)
As you know Microsoft Build conference is running on this week.
I hardly find whether 8.1 based store app has backward compatibility with 8 based app or not.
If I upgrade my Store App (what if I make update on preview period) to 8.1 based template, does it run on Windows 8 without problem?
Or, do I need to treat some special cases? I already know that Snapped ViewState was removed.
If there's no problem, please link relative article on answer. I could not find it.
No, once you migrate an app to Windows 8.1 Preview, the minimum OS version in the manifest will be set to 6.3.0 which will only allow it to run on 8.1. Windows 8 apps, on the other hand, will run on both 8 and 8.1.
There are more migration issues than the view state matters. See //build 2013 talk http://channel9.msdn.com/Events/Build/2013/3-077 for the details.
I need to create an application that runs on windows 8 pro.
When building my application with phonegap I get a resulting .xap file for Windows8 phone.
This can't be executed so I assume I need a .exe.
I also read about .appx files.
Can anyone clearify the difference between all the extensions and what my options are for a windows 8 PRO - application. Is it possible to use phonegap or is this only for windows phone?
Windows 8 and Windows Phone 8 are different platforms with some common roots. XAP is the deployment vehicle for phone, and .appx is for Windows 8.
Since PhoneGap is just a JavaScript library, it can be used with Windows 8 applications, but you'll need to incorporate it into a Windows 8 HTML5/JavaScript application. Here's a blog post that should get you on your way: http://blogs.msdn.com/b/glengordon/archive/2012/08/06/windows-8-apps-for-the-phonegap-developer.aspx
