Wix Bootstrapper Custom UI Issues

Question

I am working on a Wix bootstrapper and I need it to have a custom UI I found and have been following this tutorial https://medium.com/@rukshandangalla/how-i-created-custom-ui-using-wpf-mvvm-and-prism-for-wix-installer-5055c2b611e2 But it's incomplete and doesn't show how to link the custom UI to the bootstrapper I have tried adding it as a reference in visual studio and as a payload in the bundle but I'm not sure if this is the correct way to do it.

When I try to build it in visual studio I get the following error

Either 'Microsoft.Tools.WindowsInstallerXml.AssemblyDefaultWixExtensionAttribute' was not defined or the type defined in extension '..\Setup\bin\Debug\PETSetup.dll' could not be loaded.

This is my bundle

<?xml version="1.0" encoding="UTF-8"?>

  </Bundle>
</Wix>

And this is the main cs file of the custom UI

using Microsoft.Tools.WindowsInstallerXml.Bootstrapper;
using PETSetup.Models;
using PETSetup.ViewModels;
using PETSetup.Views;
using System.IO;
using System.Windows.Threading;

namespace PETSetup
{
    public class PETSetup : BootstrapperApplication
    {
        Microsoft.Tools.WindowsInstallerXml.AssemblyDefaultWixExtensionAttribute t = new Microsoft.Tools.WindowsInstallerXml.AssemblyDefaultWixExtensionAttribute(typeof(PETSetup));
        public static Dispatcher Dispatcher { get; set; }
        protected override void Run()
        {
            Dispatcher = Dispatcher.CurrentDispatcher;
            var model = new BootstrapperApplicationModel(this);
            var viewModel = new InstallViewModel(model, Engine);
            var view = new InstallView(viewModel);

            model.SetWindowHandle(view);

            Engine.Detect();
            view.Show();
            Dispatcher.Run();
            Engine.Quit(model.FinalResult);
        }
    }
}

What am I supposed to do to get this to work? or does anyone know of a better step by step tutorial? because the only other ones I can find are for Msi's, not bootstrappers.

Answer 1

issue 0: check how to fix the config file of your project here WiX Custom Bootstrapper Application and .NET 4.5

issue 1: the bootstrapper is launched by the wix engine at each step your cosutom bootstrapper hands back the process by calling one of the methode: you called for example Engine.Detect() and Engine.Quit() but to get the hand back you have to implement event handlers: like on DetectEnds then do your work, and then hand back to wix with like Plan check this example https://github.com/rstropek/Samples/tree/master/WiXSamples/CustomBurnUI
