Is a WinJS/Javascript + Html5 app written for Windows 8 compatible with Windows phone 8? - windows-8

Is a WinJS/Javascript + Html5 app written in javascript for Windows 8 compatible with Windows phone 8? From today's presentation, the recommended way is C#/XAML. It makes me wonder if my js app for windows 8 becomes compatible with WP8 (ofcourse with minor changes)?

Based on the information released at the June 2012 Windows Phone Summit, it appears that the development choices for Windows Phone 8 are:
XAML with C#/VB code
Native C++/C code
HTML 5 Browser Control
Based on their choice of wording, I infer that both C++/XAML and WinRT/HTML5 development models will not be available.
We'll know more once a preview of the WP8 SDK is released "later this summer".

WinJS/Javascript + Html5 app written in javascript for Windows 8 compatible with Windows phone 8?
No. Apps (not games) are still written in C#/VB.NET and XAML.
If your app runs in the browser, IE10 is able to render HTML5, but you'll not get any platform interop features.

How do build and deploy WP8 app on device which is created from Mobile First 7.1?

I made simple Test app to check direct update in Mobile First 7.1.
Added WindowsPhone8 - Universal environment. Opened created native windows8 folder in Visual Studio. Now its showing three folders namely .Shared, .Windows8(Windows8.1) and .WindowsPhone8(WindowsPhone8.1).
Now I want to create xap of WP8 to deploy on device. How to do that? In 6.1 and 6.3 it was just deploy on device. Here I am not seeing that kind of option.
1) By design of Microsoft, Windows 8 Universal project comes with 3 projects within - Windows 8.1, Windows Phone 8.1 and shared.
Note that this is different from the Windows Phone Silverlight project.
2) Direct update feature is available only in Windows Phone Silverlight and not Windows Universal.

Which platforms does Xamarin support?

I tried finding the information both on their website and on the Internet, but it appears that everywhere I look, a different list pops up.
Their front page says iOS, Android, Windows and Mac.
In their documentation (http://docs.xamarin.com/), only Android iOS,
Mac are mentioned at the docs front-page. I'm wondering does this
mean Windows has lesser priority compared to others.
On the Internet, I've found even more inconclusive information. Also,
it's hard to conclude what Windows means, mobile or desktop.
I've never used the product, but would love to try it for the game that I want to create, so I have two questions:
Can you give me a complete list of supported platforms (Android, iOS, Mac, Windows, Windows Phone, HTML5, Flash...)?
Can I target Facebook app with Xamarin?
Thanks in advance.
To update and extend Jason's answer there is now Xamarin.Forms that let us build cross-platform GUI for Android, iOS and Windows Phone. Looking at Xamarin's FormsGallery sample app I think it is fair to say that it de facto supports Windows Phone as well.
In addition to Xamarin.Forms there's always the possibility to use Xamarin.iOS, Xamarin.Android and Xamarin.Mac for platform customizations.
Xamarin.Mobile is in a preview release and supports Android, iOS and Windows Phone. It is used as an abstracted API of the native services (camera, geolocation etc).
However since you need the local SDK's installed for compilation you need a Mac computer to be able to deply for iOS. In order to compile for Windows Phone you need to use Visual Studio and the Xamarin Plugin, Xamarin Studio is not able to do this.
To conclude Xamarin supports development for
Android
iOS
Windows Phone
Mac
However not all of Xamarin's API's are implemented for all platforms.
Xamarin has three products
Xamarin.iOS - write iOS apps using C#
Xamarin.Android - write Android apps using C#
Xamarin.Mac - write Mac desktop apps using C#
Xamarin does not directly support Windows Phone apps. However, because you can write iOS and Android apps in C#, and C# is the native language for Windows Phone, using Xamarin allows you to write code that is usable across all three mobile platforms. Xamarin also provides some tools (like their Xamarin.Mobile library) that make this easier by providing a common interface to some common platform functions that will run on all three platforms.
You can write a mobile app that uses Facebook's API with Xamarin, but you cannot create a Facebook app (one that runs on Facebook).
You may find the actual list of additional platforms here.
On April 2019, it's listed as:
Android (incl. Android Wear)
iOS (incl. watchOS and tvOS)
Windows (UWP and WPF)
Linux (GTK)
Mac
Tizen
Windows Phone not supported since Xamarin 3.x

Camera API of Corona availability on Windows

I want to make an iphone app in corona which uses camera and audio recorder functionality but as far as i searched out, camera app is not supported on windows OS.
So am I not able to create such app on windows environment using corona SDK and need to switch to MAC OS??
Not being supported on windows means you cannot test on windows. If you test on the iPhone your app will work fine (if you made it correctly of course).
But you should not be developing for iOS on Windows, it is harder to debug, and you cannot upload it to apple store anyway,
You have to be on a Mac to build for iOS devices (or use a service like MacInTheCloud). Windows can only build for Android. You can develop on Windows but when you need to put it on a device, you will have to have access to a Mac.

Libgdx for Windows Phone 8

I want port my libGDX game to Windows Phone.
Can I compile my libGDX game for Windows Phone 8?
No, not directly. Currently, libGDX "only" works for Mac, Windows, Android, HTML5 (via Google Web Toolkit), and (beta) iOS.
You may be able to make the HTML5 output run on a Windows Phone (depends on how spiffy the JavaScript engine in the browser is). Then you'd need some way to package this for Windows Phone (on Android or iOS you could use PhoneGap, there may be some equivalent for WP8).
The iOS support for libGDX is actually done via a C# cross-compiler (!!?), so you may be able to use that step to build something that might run on the WP CLR. However, it looks like that won't be easy. It should be possible to use (and probably improve) other tools to translate/convert a libGDX application to WP, but doing so would probably be a lot of work.
