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.

In my work we are preparing for developing a fitness application that is supposed to run on Windows 10 (Maybe windows 8.1) and XBox One. We want to use the Kinect V2 for measuring the performance of the user while doing a workout.
I have a few questions:
1: Is it possible to develop a Windows 10 Universal App, that uses the Kinect V2 for both Windows 10 PC and XBox One - so one codebase for both products? I have read somewhere that Kinect V2 SDK is not supported for the Universal Windows Platform, but i can not understand why i should not be supported?
2: If its not possible to target the Universal Windows Platform, do we then need to target Windows 8.1 Store Apps, and develop a version for both Desktop and XBox One?
3: We want to show a fitness video that runs in the background, with a UI on top/overlay that displays the users vitals like heart-rate, intensesnes level, repetitions, and calorie burned. Can we use WPF/XAML for this, or do we need to hire a developer that excels in Unity or XNA?
4: If we hire a Unity/XNA developer, are these technologeis compatible with the Kinect V2?
This is a multi-part question but the individual parts that are relevant to you should be easy enough to answer: Kinect 2.0 works with Windows 10 development, but not currently supporting the Windows 10 UAP. Target the Windows 8.1 UAP and your app will still work on Windows 10 (and potentially Xbox One if you have access to the Xbox One dev kit, which you can only get right now through signup).

And, your question 3, yes, you can interact with the Kinect data using only the C#/XAML pipeline. You shouldn't need a Unity developer for this interaction. I did a tutorial video explaining how to get the data and if you download the Kinect SDK there are C# sample codes. https://channel9.msdn.com/Blogs/Amanda-Lange/Kinect-100-August-2015
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.
Am new to WPF .Previously was worked with Windows 8 /Windows phone application developer. I created a List application using ListBox in WPF. Since i wanted to test the application on a touch device i tried to run it's .exe file on my Windows 8 Surface tablet. I could not run my application.
Can't I run WPF application on Windows 8 tablet? Currently am working & running it using a Windows 8 PC , Where it runs. Please provide any information regarding this.
Or how we can create my application's package so that we could run it on Windows 8 surface tablet ?
For the Surface Pro tablets, you should still be able to run WPF. However, the standard tablets will only run Store Apps.
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.
I have developed a Windows desktop gadget using Silverlight (MVVM pattern) and WCF.
I want to know whether it will work on Windows 8, since there is no option as sidebar in Windows 8.
If possible please tell what should I do to make it compatible with both Windows 7 and Windows 8.
Windows Desktop Gadgets are not supported on Win8: http://www.techradar.com/news/software/operating-systems/microsoft-to-remove-desktop-gadgets-from-windows-8-1088122
You can try to reuse some parts of your code to make a Windows 8 'immersive app' with a Live Tile. The C#/XAML stack in Windows 8 is quite similar to Silverlight (but not the same). See http://msdn.microsoft.com/en-us/library/windows/apps/hh465136.aspx for a guide about the differences.
