Modernizing Legacy WPF Apps: Theming and UX Upgrades with Xceed Toolkit Plus

Modernizing legacy WPF apps doesn’t require a rewrite. Xceed Toolkit Plus lets you instantly upgrade your UI with Pro Themes, advanced controls, and XAML styling—delivering a modern, professional look in days. The result: higher user confidence, faster onboarding, and a UI that matches today’s standards, all without disrupting your core application.

Why Modernize Legacy WPF Apps?

Modernizing legacy WPF apps with Xceed Toolkit Plus is the fastest way to achieve a polished, professional UI—without a full rewrite. Outdated visuals signal “maintenance mode” to users and buyers. A dated UI drives down adoption and renewal rates, while a total rewrite is rarely viable due to cost and risk. Xceed Toolkit Plus lets you modernize the UI layer for immediate, high-impact results with minimal disruption.
