Passkeys, Local LLMs, and .slnx
This issue covers ASP.NET Core passkeys, ONNX Runtime local inference, .slnx, webhook delivery, logging practices, and AI agent engineering.
Jasen's top three picks
- 1 How to Implement Passkey Authentication in ASP.NET Core Applications
c-sharpcorner.com
Passkeys are moving from nice-to-have to expected. Useful if you want stronger auth without dragging users through password friction.
- 2 From .sln to .slnx: Why the New Solution Format Matters for Modern .NET Development
medium.com
.slnx is one of those changes that seems small until you think about tooling, merge behavior, and long-term solution maintenance.
- 3 Building a Search Platform Using OpenSearch and .NET
c-sharpcorner.com
Good architectural overview for search in .NET, especially if you're weighing indexing and query design alongside scale.
Editor's note
I kept this one deliberately broad, which is usually when the most useful combinations show up. The passkey authentication walkthrough is worth your time if you’re hardening sign-in flows, and the .sln to .slnx piece is a practical look at tooling evolution that will affect day-to-day .NET work. I also liked the host process deep dive and the webhook delivery article because both focus on the kinds of operational details that bite real systems.
