Bootstrapper, .MSI Uninstall UI doesn't show

Hello, Oleg.
I Use Wix# to create .exe-bundle, this bundle installs two packages: 1) .net4.5 (if missing) 2) my msi-installer.
As example I use "Bootstrapper\WixBootstrapper_NoU".

What i do:
1) I compile project.
2) Then I execute .exe-file first time, - it shows installation UI of the msi-file, and i install it successfully.
3) After that I execute .exe-file second time - and it DOESN'T SHOW uninstall UI of the msi-file, i wait some time and check - my program was uninstalled.

What i want:
I want to show user uninstall UI of the msi-file. If i use example "Bootstrapper\WixBootstrapper_UI", i see bootstrapper UI. What should i do? (Or is it even possible)?

Here is my code:
(object "project" is a simple msi-installer)
            string productMsi = Compiler.BuildMsi(project);
            var bootstrapper = new Bundle(@"Установщик MyProgram",
                            new PackageGroupRef(@"NetFx45Web"),
                            new MsiPackage(productMsi) { DisplayInternalUI = true })
                OutFileName = @"MyProgram.Setup",
                Version = new Version(""),
                Application = new SilentBootstrapperApplication(),
                UpgradeCode = new Guid("E1C17AD2-790F-4AE4-BE25-9DB79BDDAF74")
Thank you for your answer!

Unfortunately it is not possible.

Uninstalling is very different comparing to the other deployment scenarios. You probably noticed that all MSI authoring solutions support building Install/Repair UI but not the Uninstall one. It is because during the explicit uninstall no UI associated msi file is shown. MSI runtime displays a standard uninstall progress dialog instead. This is what is preventing Burn bootstrapper from displaying any msi UI on uninstall.

This therad also talks about the same issue:

I have captured a few points (including yours) regarding the Burn integration in this post:
