OpenSilver

OpenSilver is a powerful migration platform that enables developers to convert legacy Silverlight and WPF applications into modern web applications that run on any browser and device. Instead of requiring a complete rewrite from scratch, OpenSilver allows you to reuse your existing C#, VB, or F# codebase while transitioning to contemporary web standards. The tool preserves the original application's functionality and user interface while eliminating dependencies on outdated technologies like Internet Explorer and Silverlight plugins.

What makes OpenSilver stand out is its comprehensive approach to legacy migration. The platform includes an AI-enhanced drag-and-drop UI designer, supports enterprise-grade controls and libraries including RIA Services, and offers remarkable compatibility with Microsoft Silverlight and extensive WPF support. The latest version 3.3 introduces the ability to run Blazor components directly within XAML applications and offers MAUI Hybrid integration, providing developers with flexible modernization paths.

This tool is particularly valuable for organizations with significant investments in Silverlight or WPF applications who need to maintain business continuity while moving to modern web platforms. Development teams can achieve screen-to-screen parity, avoid retraining users, and preserve documentation while gaining the benefits of cross-platform compatibility. OpenSilver claims to save 3-6 times the time and cost compared to traditional rewrites, making it an efficient solution for enterprise application modernization.
