i have a uwp app that launches a c++ console app (not a windows runtime component or anything related to uwp). i need the uwp app to pass a file path to the c++ console app so the console app can process it. for reference, i followed these blog posts:

https://stefanwick.com/2018/04/06/uwp-with-desktop-extension-part-2/
as for the parameters, i have this code in my Package.appxmanifest file
<Extensions>
<desktop:Extension xmlns:desktop="http://schemas.microsoft.com/appx/manifest/desktop/windows10" Category="windows.fullTrustProcess"
Executable="PTSExtractionWRTPTSExtractionWRT.exe">
<desktop:FullTrustProcess>
<desktop:ParameterGroup GroupId="ExistingFile" Parameters="/existingFile"/>
</desktop:FullTrustProcess>
</desktop:Extension>
</Extensions>
and i launch the console app like so from MainPage.xaml.cs
if (ApiInformation.IsApiContractPresent("Windows.ApplicationModel.FullTrustAppContract", 1, 0))
{
// store command line parameters in local settings so Launcher can retrieve them
ApplicationData.Current.LocalSettings.Values["parameters"] = filePath;
var appData = ApplicationData.Current.LocalSettings;
await Windows.ApplicationModel.FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync("ExistingFile");
}
the problem is that the filePath variable i’m sending is getting stored in the C:Users087AppDataLocalPackages930191-5d12-44d5-81c3-808263a5b2f9_qe1bgctg42gkjSettingssettings.dat
file with this path and i can’t find a way to access this file from the c++ console app. what’s being sent as arguments to the c++ app is "/existingFile"
from the Package.appxmanifest flie. how can i retrieve the real parameter?
