Home Archive WebAssembly, security, and backend design – .NET News Daily Issue #454 (May 13, 2026)

Editor's note

I put together another deliberately mixed issue today, and the Copilot Studio move to .NET 10 on WebAssembly stood out for the real-world performance angle. I also liked the production-ready backend walkthrough because it pulls CQRS, domain events, resiliency, and observability into one practical design. On the fundamentals side, the LINQ deferred execution piece and the C# virtual/partial/override refresher are useful reads for teams mentoring newer developers.

Jasen's take on today's picks

Machine Learning for C# Developers Made Easy

A friendly on-ramp for .NET developers who want to get productive with ML concepts and tools without switching ecosystems.

Copilot Studio gets faster with .NET 10 on WebAssembly

This is the kind of case study I like: concrete migration work, browser-hosted C#, and measurable payoff from .NET 10.
