Can I make an application using Codename One for Android, iOS ,and Windows Phone 8 from a single code base, but yet provide support for windows phone 8 feature like live tiles ?
You should be able to use native features using the NativeInterfaces concept however, I have no idea if live tiles would specifically be supported.

I have a Java Swing based video game (though more like Java AWT, since most of it is graphics movement of icons), that I would like to port to a Cell Phone. Android, iOS, or even Windows Phone.
I have read that JavaFX supports this. Though the posts I read were a few years old. Does anyone know status of JavaFX on current versions of Android, iOS, or even Windows Phone?
Thanks!
JavaFX requires a JRE to run on. Neither of those three mobile platforms support this natively. So you will need to return to a framework that allows you to do exactly that.
The most positive lead at the moment seems to be the JavaFXPorts from the Gluon project. However as far as I am aware, this currently only supports iOS and Android.
I have just installed Windows 8.1 and then installed Visual Studio 2013 Community Edition.
I tried to create a Windows Phone app and found out that there are two ways of creating it (in fact 3 if you count Universal Apps if I am not wrong)
Windows Phone
Windows Phone Silverlight
Can someone please tell me what exactly is the difference between these two? I read a couple of articles but still don't understand and this whole thing is very confusing.
When I tried to create a Windows Phone Silverlight project then it asked me whether I want to target 8.0 or 8.1.
When I tried to create Windows Phone project then it asked me to get a Developer license and didn't ask about version 8.0 or 8.1.
What shall I chose if my aim is to create an application for mobile devices (tablet/phones) that will run on maximum devices running Windows Phone 8 version?
Windows Phone 8 Silverlight is the older UI on Windows Phone 8. WinRT XAML is used for Windows Store Apps(these are Universal Apps). Windows Phone 8.1 Silverlight is a bit different as explained here.
Windows Phone Silverlight, although older, is better in some ways. If your aim is to develop an app that is targeted only for phones and that doesn't have any use getting ported to Win8/RT, go with Silverlight. Background Audio is a mess in WinRT. Speech Recognition with Cortana is worse.
The controls of WinRT XAML are buggy. For example, there is a clear performance degradation of MapControl in WinRT XAML, whereas, in Silverlight, this is smoother.
On the other hand, Windows Store Apps have .NET Native, which converts C# to native C++ code, resulting in performance gains.
For a beginner, I would advise starting with Windows Phone 8 Silverlight apps.
Windows Phone Silverlight is the "old" platform that WP8.0 apps are built on. It asked you to target 8.0 or 8.1 because WP8.1 has a hybrid mode that lets you build WP8.1 apps but still have access to the Sliverlight API if you had a whole lot of legacy code you didn't want to port over just yet.
Windows Phone is the (mostly) universal platform for WP8.1 that is based on Windows Runtime.
I have to create an application with metro design on vs2010 and windows 7.
The application should work both on pc and device without internet.
Initially i though of wpf but i do not know if it works on Mobile.
Please let me know how i can develop once such standalone application for
both device and PC also
Unfortunately, there is not a single platform that targets both PC and Phone...although, the presumption is that Windows Phone and Windows Store applications are moving toward a unified foundation.
Windows Store applications unfortunately don't run on Windows 7. Only Windows 8 and above, but the advantage is they work with the desktop version as well as the tablet version of windows.
If you want to target windows 7 and say windows phone as well, your best bet is to use portable class libraries to create a common "core" for the application. And use WPF for the desktop which has a lot in common with XAML for Windows Phone.
If you want to target windows phone 8, you have to use Visual Studio 2012 or above.
Pretty old question, but in case anyone is still blindfolded, there is UWP.
Furthermore, if you want to have XAML and C# deployed as native apps in a variety of platforms (UWP, Droid, iOS, WinPhone), be sure to check out Xamarin, which now belongs to Microsoft, and follows the awesomeness of open-source MIT just as the entire .NET does now.
Can existing apps (both web and desktop apps) using Silverlight run on Windows 8? How about Windows RT?
If it's not possible, what would be the path of least resistance to make it work? (Viz., how to get it working on Windows 8/RT, not caring about whether it'll work on Windows 9 or not.)
Existing Silverlight applications can run in the Windows 8 Desktop, but cannot run as part of a Windows Store application. Only Windows Store applications can run on Windows RT (with exception of Office apps delivered by Microsoft).
Path of least resistance would be leveraging your assets - it's C#/VB and XAML still - within the Windows RT framework.
You might check out this Deep Fried Bytes episode, and there are other blog posts as well to give you some guidance. There's also an article on the Dev Center focused on Windows Phone 7 Silverlight to Windows 8, but much should be application to your scenario as well.
You WPF and Silverlight application work fine on Windows 8, but not in the Windows store, which needs only Metro Applications.
But you can more and less easily port your Silverlight app to Metro : you keep XAML files, and you change the code behind with new objects defined ine the Windows 8 libraries.
I've heard that Windows Phone 7's user interface (UI) is completely based on Silverlight. Can anybody confirm this? Or it is implemented by other frameworks?
Windows Phone 7 will support developing apps in either Silverlight or XNA.
Are you asking if the shell, etc that comes on the phone itself is written in Silverlight? My first question would be "why does it matter what Microsoft used?" It's probably a good bet that they leveraged it, but I doubt they did everything in SL. At some point they have to get down to the OS. For example, I doubt the built-in media player core or Office apps are SL.
Looking at the unlocked emulator image contents would certainly let you deduce which parts were developed with what technologies. I leave that exercise to you.
Indeed Silverlight is used for third-party apps on Windows Phone 7, plus XNA is supported too as mentioned.
However the Office apps and some first-party applications are written using the Iris framework which is an internal only developer framework similar to WPF, it is the same framework used for the Zune Software (Dorado) which is used to sync to a Windows Phone 7 device.
Yes it is based on Silverlight
I can tell you one thing, they are using Expression Blend (or a modified version of it) for parts of the core UI design. You can see the developers using this on one of their promo videos.
