The fix was simple and it is done already.
If you really keen you can grab "src\WixSharp.Samples\WixSharp.UI.dll" v1.0.43.2 from Git. It already contains the fix. But I will not have time to do the NuGet release until next week.

Your code is absolutely correct. It is the way of integrating the WiX extensions. It's just that Wix# defect prevented you from succeeding.
