public static class MetadataUpdateThe .NET runtime's hot-reload callback: what dotnet watch calls once it has replaced a method body in the running process.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
This is the other half of the markup channel, and the half that is not ours. Editing a .vxml regenerates a C# file, which changes Build, which the runtime delivers here — and only then is there anything new to run. A watcher over .vxml could see the edit sooner and do nothing useful with it.
⚠ Hosts are held weakly. A static list of every document ever created is a leak with a development-only cause and a production-shaped consequence, and the handler has no idea when a window closes. A collected host simply stops being reloaded.
