Question

Can the exisiting Windows Phone Apps run on the new Windows 10 Mobile devices?

Do they need to be recompiled?

They haven't been released, so there's nothing I can say about them.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

How about Win Phone with Win 10 Tech Preview? -- some models of Windows Phone, like Lumia 630. 830, etc. are listed as support Win 10 Tech Preview: any status of existing Win Phone 8 apps running on Win 10 Tech Preview?

Thanks,

William

Currently, Windows 10 for phones is backwards compatible all the way to WP7 apps. Any Windows Phone app should work with Windows 10 (phone version), perhaps with a few exceptions.

But as Matt said, Windows 10 is not released and things could change. But I can't imagine anything changing that would affect compatibility.

That's not entirely true. Windows Phone 7 apps that were compiled solely on the Windows Phone 7 SDK will not run on the Windows 10 Technical Preview. Windows Phone 7 apps can still target Windows Phone 7 devices, but must be compiled using the Windows Phone 8 SDK in VS2012 or above.

Most Windows Phone 7 apps have probably been compiled with the method in that link already, but for those that weren't, such as people using Windows 7 and VS2010 to develop apps, those apps will need to be recompiled in the WP8 SDK. No changes to code are necessary though.

Answer 5

Windows Phone 8 Silverlight, Windows Phone 8.1 Silverlight and Windows Phone Runtime applications should run with no problems on Windows 10 for Phones (not for PCs and Tablets).

However, Microsoft had recently published the Windows 10 Technical Preview SDKs, so the developers can see, what is going to be released.

According to documentation I mentioned:

https://dev.windows.com/en-us/windows-10-for-developers

you will have to make some changes in the code in order to run the application on every Windows 10 device (phone, tablet, PC or whatever).

As this is the Technical Preview release now, things might change when the final version arrives, but for now we have a nice preview of what developers will have to work with.

I hope this helps
