According to Show Confirm Dialog When User Close UWP App, i used namespace "rescap" in my UWP app.
<Package
xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"
xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest"
xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10"
xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
IgnorableNamespaces="uap mp rescap">
......
<Capabilities>
<Capability Name="internetClientServer"/>
<Capability Name="privateNetworkClientServer"/>
<Capability Name="internetClient"/>
<rescap:Capability Name="confirmAppClose" />
</Capabilities>
</Package>
But now i can not pass the "Windows App Certification Kit - Test"
How can i pass this test without removing this "Restricted namespace"?
