OpenSilver: Open-Source Implementation of Silverlight

An open-source implementation of Silverlight, providing similar functionality for building rich internet applications using C# and XAML, as an open-source alternative to Microsoft's ecosystem.

What is OpenSilver?

OpenSilver is an open-source re-implementation of Microsoft's Silverlight platform for building rich internet applications (RIAs). Like Silverlight, OpenSilver allows developers to use C# and XAML to create web apps with desktop-like functionality and interfaces.

As an open-source project, OpenSilver provides an alternative for developers who want to create Silverlight-like apps but avoid locking themselves into Microsoft's ecosystem. The code is available on GitHub for anyone to view, modify, or redistribute under an MIT license.

Some key capabilities and benefits of OpenSilver include:

• Ability to create fluid UI/UX experiences powered by C# and XAML code
• Use of GPU-accelerated graphics for smooth animations and video
• Small runtime that can be distributed as part of self-contained applications
• Cross-platform support for Windows, Mac, and Linux
• An open-source community providing free hosting of OpenSilver apps
• Freedom from being tied to Microsoft's roadmap or licensing terms

While OpenSilver supports much Silverlight functionality, there are some limitations in terms of things like 3D graphics, database access, and integration with certain browsers. But for many RIAs it provides a compelling open alternative to build on.
