Obtaining the URI argument within a registered uap:protocol executable

Question

I have a C# WPF application and I've referenced that inside a MSIX package. I've also registered a URI protocol within the Package.appxmanifest of my MSIX package the following way:

<uap:Extension Category="windows.protocol" EntryPoint="AppLauncher"
                    Executable="AppLauncher\AppLauncher.exe">
                    <uap:Protocol Name="app-drive" >
                    </uap:Protocol>
</uap:Extension>

The goal is when I type app-drive:\\C:\test.txt into the file explorer or a browser for my executable to launch and within it I want to have the following string accessible C:\test.txt.

After I install my MSIX package and enter that string anywhere, my program launches correctly but that argument is nowhere to be found.

Ways I've tried to obtain it so far:

1.

[STAThread]
static void Main(string[] args)
{
 // args[0] contains "-ServerName:App.AppXd****.mca" string
}

2. Environment.GetCommandLineArgs()

3. protected override void OnStartup(StartupEventArgs e)

All of these contain only the string "-ServerName:App.AppXd****.mca" as a first argument.

Note that I cannot use Windows.ApplicationModel.AppInstance.GetActivatedEventArgs() since my application is not UWP.

Any suggestions?

Edit: Found the solution. Turns out in order for the parameter to be passed to the executable the EntryPoint has to be EntryPoint="Windows.FullTrustApplication"
