The same bug exists in release 2.0.3.
We need a documentation how to avoid this issues #668

Yep. I've had to copy some of WPFUI's code to avoid this issue, as I can't port my entire app in one go.

This is particularly an issue (for me) with calls hardcoded to Application.Current.Resources.

Perhaps it would be better if you could have an IWpfUiResourceService that you pass to those methods, with a default implementation that points to Application.Current.Resources, but a way for you to supply your own.

Perhaps it would be better if you could have an IWpfUiResourceService

And this IWpfUiResourceService should be public to be able to change theme colors at runtime.
