Windows 10 Universal App Feedback

Question

How in Windows 10 Unviersal Application invoke Feedback Page in Store? In Windows Phone 8.1 i used

 await Windows.System.Launcher.LaunchUriAsync(
         new Uri(@"ms-windows-store:reviewapp?appid=" + Windows.ApplicationModel.Store.CurrentApp.AppId));

but now it's not worked for me

Answer 1

Rather than reference an appid in the link use the PackageFamilyName

ms-windows-store://review/?PFN=xxxx 

where xxxx comes from Windows.ApplicationModel.PackageId.FamilyName
