OpenSilver SDK

Project templates and XAML Designer for creating OpenSilver applications.

OpenSilver is an open-source platform that enables .NET developers to build cross-platform applications using familiar C# and XAML. Originally created as a modern reimplementation of Microsoft Silverlight, it has evolved into "WPF Everywhere" – extending beyond Silverlight's scope to bring Windows Presentation Foundation capabilities to virtually any platform . The platform compiles to WebAssembly and JavaScript, allowing applications to run natively in all modern browsers without plugins while supporting deployment to mobile and desktop environments.

OpenSilver empowers developers to:

• Modernize existing WPF, Silverlight, LightSwitch, and Windows Forms applications
• Create new business applications with a single codebase for web, mobile, and desktop
• Develop with C#, VB.NET, or F# using familiar XAML-based UI design
• Leverage the AI-assisted WYSIWYG designer in Visual Studio and VS Code

For developers, OpenSilver offers the productivity of WPF with the reach of web technologies, eliminating the need to learn multiple UI frameworks while enabling deployment across virtually any device or operating system.
