Elegant work-around for omitting most parameterless constructor logic for live preview?

[TangDave]

Most of my windows use a single parameterless constructor, but for the live preview I really don't want to include the logic to populate or modify the window at runtime. Does anyone have an elegant solution to this?
I could make a new constructor with a useless parameter which then calls the parameterless constructor, which only has the InitializeComponent call, but this is an ugly hack to work around the way live preview works.

Found a solution, which seems to work well:

I just add this to the constructor, immediately after the call to InitializeComponent:

		//want to exit here for Avalonia Live Preview mode:
		if (Avalonia.Controls.Design.IsDesignMode)
			return;
