I have a completed application and I want to publish, but I'm afraid of having to redo the project in windows phone 8.0 Silverlight. Currently I am having problem in admob where the emulator it works and the device gives the message "nofill". Does anyone know?

I have a windows app that's running for a while and recently when I'm trying to deploy the application on windows phone running windows 8.1 OS(using visual studio 2013 and windows phone application deployment) I'm getting the following error:
"You have installed the maximum number of development apps. These apps are installed to your device when you start them in Visual Studio or when you use the App Deployment Tool. Please uninstall one of them and then try again."
I've tried to reset the phone, renaming the app and the phone on windows explorer, unregister & register the phone and also uninstalling all the other applications on it.
The problem is happening on two different devices Nokia Lumia 630 & Nokia Lumia 920.
Is there another way to approach this?
Thanks in advance
This issue has been fix now and we can register our Windows Phone 8.1 for developing:
Could you please try to unregister the Phone from the Dev Center and register Phone again to see if it works?
I've been developing a Windows Phone 8.1 app using C#/XAML. My configuration is up-to-date Windows 8.1 PC + Visual Studio 2013.
I can test my app on WP 8.1 emulator that comes with VS2013, and also no problem deploying it on physical Windows 8.1 device.
However the app also runs on Windows 10 Mobile because the platform currently allows it that way. Which is good except, my app doesn't work as intended since the device got Windows 10 Mobile Anniversary Update.
I don't know if the problem is in Windows or in my app but that's not important here.
I need to create a hotfix for the issue. And here comes the question. Is there a way to deploy WP 8.1 app to Windows 10 Mobile without submitting it to the store first, without upgrading to Windows 10, and preferably without upgrading to VS2015?
UPDATE The reason I want to deploy WP 8.1 app to Windows 10 Mobile is to test if my patch fixes the issue manifests with Windows 10 Mobile. At the moment I don't understand where is the problem and keep submitting the fix attempts to the store is not ideal.
Thanks.

Yes, it is possible to deploy WP8.1 app to the Windows 10 Mobile without submitting it to store and without upgrading to Windows 10 and without upgrading to VS2015. But you need to make sure you have the Windows 10 Mobile device for you to test.
If the Windows 10 Mobile device is in your side, you can unlock the Windows 10 Mobile device and deploy your app to the Windows 10 Mobile device by using the USB with the same method that you deploy it to the Windows Phone 8.1 Mobile device.
Or you can try to sideload your app on the Windows 10 Mobile device without submitting it to the store by using the Application Deployment tool. For more information, please try to refer to this article:How to deploy Windows Phone 8.1 apps with the Application Deployment tool.
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.
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.
I've been working on a Windows Phone 8 app, which I now want to change to be Windows Phone 8.1. How can I do this?
Should I create a new Windows Phone 8.1 app and copy all my existing files into it? Or is there an automated way for me to upgrade the existing solution to 8.1?
There are two ways to do that:
like in comment - right click on oyour project and you should see Retarget to Windows Phone 8.1
or you can open Properties window of your project and the in dropdown box Target Windows Phone OS version you can choose Windows Phone 8.1
In every case the VS should ask if you are sure to do that - it's one-way operation, so it's worth to make a backup of your solution. As WP8.1 has backward compability, in most cases there shouldn't be any problems.
Some clarification for the followers:
As WP8.0 apps are Silverlight, after retargetting it will still be a Silverlight app but WP8.1 (some new features and enhancemens).
Thought, if you want to retarget to WP8.1 Runtime, it's a totally different thing - it's a different type of an app, different API and more. You will have to port it manually. Note that not all features from WP8.0 are yet available in WP8.1 Runtime - here is a good article about that.
