Internal tools often ship with bare-minimum config screens and then rot: fields scatter across dialogs, validation is inconsistent, and adding new settings means weeks of UI plumbing. WPF PropertyGrid from Xceed’s WPF Toolkit Plus is the silent time-saver that flips this script. You bind a POCO settings object, get production-ready editors instantly, then layer in custom editors, attributes, and validation as needed. Result: a consistent, branded, MVVM-friendly admin panel without a mountain of XAML.
