Property seems to change per user's selection, but conditioned files are not being deployed

问题

In our installer, we want to deploy one of two files, according to a decision that the user should make during the installation.

I am able to change the property during run-time, via a WixForm using radio buttons, and even to confirm that the bound property indeed changes (using a CustomAction that shows a MessageBox, checking the expressions session.EvaluateCondition($"TYPE_OF_PKG=\"ABC\"") and session.EvaluateCondition($"TYPE_OF_PKG=\"XYZ\"")).

However, it doesn't seem to affect the conditioned files - they are simply not deployed (unless I explicitly set the "TYPE_OF_PKG" Property's value to e.g. "ABC" instead of "NONE").

These are the two feature, abcFeature and xyzFeature:

var abcFeature = new Feature("ABC_PKG") {
    Condition = new FeatureCondition($"TYPE_OF_PKG=\"ABC\"", 1),
    Attributes = {["AllowAdvertise"] = "no"},
    AllowChange = true,
    IsEnabled = false,
};

var xyzFeature = new Feature("XYZ_PKG") {
    Condition = new FeatureCondition($"TYPE_OF_PKG=\"XYZ\"", 1)
    Attributes = {["AllowAdvertise"] = "no"},
    AllowChange = true,
    IsEnabled = false,
};

And that's the project definition:

var files = new WixObject[] { new File(abcFeature, "abc.exe"), new File(xyzFeature, "xyz.exe") };

new Project(myPorjectName, files)
{
    Properties = new[] { new Property("TYPE_OF_PKG", "NONE") { AttributesDefinition = @"Secure = yes" }
    Features = new[] { abcFeature, xyzFeature },
    CustomUI = CustomUIBuilder.BuildPostLicenseDialogUI
    (
        dialogDefinition,
        new DialogAction[] { new ShowDialog(NativeDialogs.InstallDirDlg) }
    ),
}

Where in dialogDefinition (inherited from WixForm), we have two radio-buttons, bound to the TYPE_OF_PKG property, to display the option to the user (and change its value per the user's decision):

this.RadioButtonsGroup.BoundProperty = "TYPE_OF_PKG";
this.RadioButtonsGroup.ControlType = WixSharp.Controls.ControlType.RadioButtonGroup;
this.RadioButtonsGroup.EmbeddedXML = @"
<RadioButtonGroup Property=""TYPE_OF_PKG"">
    <RadioButton Value=""ABC"" X=""0"" Y=""0"" Width=""400"" Height=""20"" Text=""ABC"" />
    <RadioButton Value=""XYZ"" X=""0"" Y=""20"" Width=""400"" Height=""20"" Text=""XYZ"" />
</RadioButtonGroup>";
this.RadioButtonsGroup.Hidden = false;
this.RadioButtonsGroup.Id = "RadioButtonsGroup";
this.RadioButtonsGroup.Location = new System.Drawing.Point(12, 69);
this.RadioButtonsGroup.Name = "RadioButtonsGroup";
this.RadioButtonsGroup.Size = new System.Drawing.Size(466, 125);
this.RadioButtonsGroup.Text = "What to install .wixText?";
this.RadioButtonsGroup.Tooltip = null;
this.RadioButtonsGroup.WixAttributes = null;
this.RadioButtonsGroup.WixText = "What to install .wixText?";

Any idea how to make the selected file deployed?
