Presence of the DefaultStartPage does not guaranty the app is written in HTML

[journeyman]

In other words this property returns wrong PackageType for some apps (try Viber as example, it has StartPage AND is written in XAML/C#, not html/js)

internal PackageType Type
        {
            get
            {
                if (this.FoundStartPage)
                    return PackageType.Html;

                if (this.XamlFiles.Any())
                    return PackageType.Xaml;
                else if (this.JsFiles.Any())
                    return PackageType.Html;
                else
                    return PackageType.Unknown;
            }
        }
