Your Silverlight application has no browser left to run in.

Where you are

Microsoft ended Silverlight support on 12 October 2021. No current browser loads the plug-in. Every Silverlight line-of-business app is now either frozen on an old machine with an old browser, or being rewritten — and the rewrite is where things go wrong, because the people who knew what the app actually did have usually left.

What I do about it

I have shipped on Silverlight and I have migrated off it. The exit is usually a modern .NET web front end — Blazor or ASP.NET Core — over the same database, moved one screen at a time so the business keeps running on the old app until the new one has proved itself. Where the app was generated (LightSwitch, WCF RIA Services), I know what the generator produced, which is what makes the exit tractable rather than a rewrite from a blank page.
