New Post: Upgrade through Managed BA keeps the older version entry in ARP

Hello Oleg,

That I am already doing. Please look at the upgrade bundle code -

    class Program
    {
        static void Main()
        {
            string productMsi = BuildMsi();

            var bootstrapper =
              new Bundle("MyProduct_1",
                  new PackageGroupRef("NetFx40Web"),
                  new MsiPackage(productMsi) { DisplayInternalUI = true });
            
            bootstrapper.Version = new Version("1.1.0.0");
            bootstrapper.UpgradeCode = new Guid("6f330b47-2577-43ad-9095-1861bb25844b");
            bootstrapper.Application = new SilentBootstrapperApplication();
            bootstrapper.PreserveTempFiles = true;
            bootstrapper.Build("MyProduct.exe");
        }

        static string BuildMsi()
        {
            var project = new Project("MyProduct_1",
                             new Dir(@"%ProgramFiles%\My Company\My Product",
                                 new File("Program.cs")));

            project.GUID = new Guid("6fe30b47-2577-43ad-9095-1861ba25889a");
            project.UpgradeCode = new Guid("6f330b47-2577-43ad-9095-1861bb25844b");
            project.Version = new Version("1.1.0.0");

            project.MajorUpgrade = new MajorUpgrade()
            {
                AllowDowngrades = false,
                DowngradeErrorMessage = "Lower version",
                AllowSameVersionUpgrades = false,
                Schedule = UpgradeSchedule.afterInstallValidate
            };

            return project.BuildMsi();
        }
    }

The version of older bundle and msi is 1.0.0.0 and the MSI's project.GUID is different for both versions. I've kept the UpgradeCode same.
