Latency, validation, and agent tooling
A varied .NET roundup with ASP.NET Core performance, validation patterns, REST API guidance, Blazor modernization, EF Core, and agent tooling.
Jasen's top three picks
- 1 Latency Is a Feature, Not a Bug
medium.com
Latency isn’t just a metric here—it’s part of the API design conversation.
- 2 Modernize ASP.NET Web Forms UI to Blazor with AWS Transform
news.google.com
A useful modernization path for teams still carrying Web Forms baggage.
- 3 Stop writing all validation logic inside your .NET Controllers
medium.com
A good reminder that validation belongs closer to the boundary than your controller.
Editor's note
I curated a pretty classic mixed bag today: performance, architecture, validation, and a bit of platform news. The ASP.NET Core latency piece and the EF Core ToArrayAsync vs ToListAsync note are both practical reads if you care about where time really goes. I also liked the AWS Transform Web Forms to Blazor item and the Advanced Security work-item linking update for teams juggling modernization and fixes.
