I created a simple application that updates when we change timezones.
The application runs without errors in both the Windows Phone 8.1 emulator and real phone, but When in Windows 8.1 I get this error:
This is my project (wrote with VS2015 for Windows Universal 8.1):
My Project Files
source of Runtime Component:
Source code
If possible can you help solve this for Windows Universal 8.1 as this file is only for Windows Phone 8.1.
I'm sorry for bad English.
Per the documentation this is not supported on Windows 8.x.

Hope You are doing well.
Actually i have created one windows phone 8 application. So for testing i have installed the .xap file locally into windows phone 8 and it is working fine. But if i am going to install that .xap package in windows phone 8.1 or later it is not getting installed.
I have made research and found that the windows phone 8.1 and later OS version devices are accepting the APPX Package. They will not allow to install .XAP locally. Now the scenario is like that my client wants to test this application in windows phone 8.1 device.
So, Can anyone help me out that how can we install locally XAP package into windows phone 8.1 device?
Awaiting Response. Thanks in advance.
You can sideload your .xap package on Windows Phone 8.1 device using Windows Phone Application Deployment Tool (for 8.1).
Before installing , you need to ensure the device has been registered for development. You can use Windows Phone Developer Registration (8.1) to enable your device for development.
And you could search for the tool from the Windows 8.1 start menu.
I can't find any SQLite.Net.Platform library that works with Windows Phone 8.1.
These are not working:
https://www.nuget.org/packages/SQLite.Net.Platform.WindowsPhone8/
https://www.nuget.org/packages/SQLite.Net.Platform.WinRT/
https://www.nuget.org/packages/SQLite.Net.Platform.Generic/
https://www.nuget.org/packages/SQLite.Net.Platform.Win32/
Any workaround?
WinRT platform is compatible with Windows Phone 8.1 projects. You can copy the sources to your platform specific project and instantiate the connection using SQLitePlatformWinRT class.
Ok so I got windows 8.1 nextbook to test on. I created some basic browser app in visual studio running on virtual windows server 2012 r2. My main machine is windows 7. When I connect with USB cable nothing happens (who could have predicted that). I thought I could deploy my app on tablet and do a debug like that but haven't find a way to do it. Anybody here with experience in this scenario, I googled everywhere and the only thing I found is that documentation sucks
You cannot run a Windows Phone app on Windows. You need a Windows Phone or a Windows Phone emulator to run the Windows Phone app. To run on Windows you need to write a Windows Store app. Windows 8.1 on a tablet is the same as Windows 8.1 on a desktop or laptop computer.
In your case you'll probably need a physical Windows Phone since you are already running virtualized. The Windows Phone emulator is a Hyper-V image and is not supported nested in a Hyper-V guest OS.
If you write a Windows Universal app then the code will be mostly the same for the Windows and Windows Phone targets (the UI layer is usually different), so you can write and test the bulk of the app as a Windows Store app to run on your tablet and then recompile for Windows Phone.
everytime I try to start my app on my Lumia 1020 I get this error:
Error: DEP6250 : The Device runs on a not supported version of the OS
(I translated it from german...)
I "unlocked" my phone a few minutes ago so I think that this won't be the problem.
I also searched for an update but everything is fine...
I used the free Visual Studio express 2013 for store developers
Does anyone have ideas?
Your problem is that you are probably trying to deploy a Windows Phone 8.1 app to a device running Windows Phone 8.0. That is not possible. You need to Either create a Windows Phone 8.0 app and run it on the device or update your device to Windows Phone 8.1 in order to run WP8.1 apps. Windows Phone 8.0 apps will work on WP8.1 but the other way around will not happen.
This is what exactly is did:
Installed windows phone 8.0 SDK.
Installed windows phone 8.1 SDK(By first installing VS 2013 professional edition and later installing update R2).
After that 8.1 application xap deployment is failing
Unable to deploy xap on windows 8.1 phone using 8.1 deployment tool “Error-package failed updates, dependency or conflict validation”
The phone i am using is 8.1 updated
Can you please let me know if iam missing something?
Thanks in advance
Using Windows Phone Application Deployment (8.1), I just ran into same issue. I had tried to install an appx package which was built for Store in Release Mode.
I then realised I was trying to install an ARM build onto the emulator which needs an x86 build to run.
So instead I deployed the ARM Release Mode .appx to a physical device so I could test what I needed to test.
Hope this helps!
Not a real answer but an un-explained work around. I've recently started developing against windows phone. I am working on a Windows 8.1 machine that was previously a Windows 8 machine, previously using VS 2012 to develop against WP 8 and now using VS 2013 to develop for WP 8.1.
At intervals I start to receive the same error as reported by the question, both when deploying our WP 8.1 app to an emulator and when trying to run or debug our WP 8.1 unit tests. So far it's been resolved each time by restarting VS 2013 (and the emulator). Restarting the emulator alone has sometimes been sufficient but not always. I have not checked whether it works against a concrete device. More significantly I have no idea why deployment breaks or stopping/starting resolves it...
Our application and unit tests are WP 8.1 silver light projects and use SQLite.
