About This Site

Silverlight China dates back to the era when Microsoft Silverlight was a serious platform for rich web applications, and this domain served the developer community that grew up around it. The plugin era ended — Silverlight's support ran out in 2021 — but the site continues as a reference for the people who deal with what was left behind.

Today the site is aimed at developers, IT staff, and managers who have inherited a Silverlight application and need to understand their options. The guides cover what end-of-support actually means, why plugin-based apps no longer load in current browsers, and how the modern replacements — Blazor, WPF, and WebAssembly-based approaches — differ from one another. The interactive migration-complexity checklist gives a rough, honest first read on how large a modernization effort might be.

Everything published here is reviewed reference material written from publicly documented, durable sources — chiefly Microsoft's own lifecycle and developer documentation. It is background reading, not professional consulting. Migration projects vary enormously with the specifics of a codebase, so treat these pages as orientation, and bring in your own engineers or a qualified consultant before committing budget to a particular path.
