Windows 10 launched today and with it comes a new SDK for building “Universal Apps”. This new SDK comes with a lot of new functionality. One of those pieces is a new way to set the wallpaper of a device. This new API is available on the new UserProfilePersonalizationSettings class. This class is used for setting the lockscreen, and the device wallpaper. The new UserProfilePersonalizationSettings class has a TrySetWallpaperImageAsync method that accepts any local StorageFile (I have not been able to set the wallpaper using the FileOpenPicker). This means you can save an image to the local or roaming folders, or use an existing image packaged with your app.
var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/AwesomeWallpaper.jpg"));await Windows.System.UserProfile.UserProfilePersonalizationSettings.Current.TrySetWallpaperImageAsync(file);
This example uses a file packaged with the app in the Assets folder.
You should check if the device has the ability to change the wallpaper. I’m guessing this is in place for future Windows settings.
if (Windows.System.UserProfile.UserProfilePersonalizationSettings.IsSupported())
{ var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/AwesomeWallpaper.jpg")); await UserProfilePersonalizationSettings.Current.TrySetWallpaperImageAsync(file);
}
Now go and create some amazing wallpaper apps for Windows 10
