Home Archive Copilot, .NET 11, and WebAssembly gains – .NET News Daily Issue #458 (May 19, 2026)

Editor's note

I pulled together another deliberately mixed lineup today, with platform releases, servicing guidance, and a heavy dose of Copilot tooling. The .NET 10 WebAssembly migration story is worth your time because it shows practical performance wins from a real production move, and the .NET 11 Preview 4 post is the broadest snapshot of where the stack is heading next.

If you’re tracking Microsoft’s agent story, this adds context around Copilot Studio, apps, and employee experience scenarios.
