How do I set the target Device Family for my Universal App Project

I made an Universal App but I only want to publish it for Desktops and not for Phones yet. I also have a Windows Phone 8 App of the same name that I want to keep for all windows phone 8.1 and windows phone 8 Users. How can I accomplish this? The store just doesn't seem to have any options to allow this.
Any help?
Windows 10 Mobile is still in preview. Only Desktop has RTMed. When Mobile is available there should be a checkbox on the dashboard. See Device families at https://msdn.microsoft.com/en-ca/library/windows/apps/mt148548.aspx#dist_vis
You can also limit the DeviceFamily in your manifest. See https://msdn.microsoft.com/en-us/library/windows/apps/dn986903.aspx
The Windows 10 app won't run on Windows Phone 8.1 so those users will get the 8.1 version even once the Windows 10 Mobile app is p published

How to call calculator in windows phone 8?

I have to create calculator in windows phone 8.
I need api or DLL to call it from windows phone 8.
Is it available calculator for WP8?
Any reference or idea should help me a lot.
Thanks in advance.
I'm afraid this is not possible with the Windows Phone 8 SDK: for launching apps/services, you need to use Launchers but in the launchers list, there isn't the calculator.
On Windows Phone 8 where you have access to more launchers via URI schemes, there is no way to launch the calculator.
It seems like you will need to create your own calculator. Like an exciting one shown here:

windows phone8.1 support winjs/javascript as native already?

I'm wondering if the Windows Phone 8.1 SDK supports WinJS? I saw there are some news that windows phone 8.1 start to support WinJS
If so, I will move to WinJS for WP and WinRT both.
Your comment welcome
Yes, the combination of Windows Phone 8.1 and WinJs 2.1 will allow you to build cross platform WinJs based applications.

Universal apps written in Xaml also will be a very good way to share code across the two platforms with minimal changes.
