Environment variables in MSIX package wont be used by AVD session host

Hi OneFiftyLashes 

As I mentioned in my previous comment, we had created a test application. The config file was in the format:

{
    "applications": 
    [
        {
            "id": "ENVVARIABLETEST",
            "executable": "VFS/EnvVariableTest.exe"
        }
    ],
    "processes": 
    [
        {
            "executable": "PsfLauncher.*"
        },
        {
            "executable": ".*",
            "fixups": 
            [
                {
                    "dll": "EnvVarFixup.dll",
          	        "config": 
                    {
                        "envVars": 
                        [
                            {
                                "name": "Test1",
                                "value": "Value1",
                                "useregistry": "false"
                            },
                            {
                                "name": "Test2",
                                "value": "Value2",
                                "useregistry": "false"
                            },
                            {
                                "name": "Test3",
                                "value": "Value3",
                                "useregistry": "false"
                            }
                        ]
                   	}
                }
            ]
        }
    ]
}
