Hey #dotnet people with knowledge of System.Text.Json!

How many types can a TypeInfoResolverChain contain before it gets useless? Some things like HttpJsonOptions only allow one JsonSerializerOptions and so I have to chain all those generated contexts into one (100s of types).
Is that ok? #json

Today we ship Aspire 13! Why 13? It’s a number that’s bigger than 10 but less than 14.

It marks the start of a new chapter for the project. We’re expanding beyond .NET, bringing the same, code-centric experience to Python, JavaScript, and more.

Hey #dotnet, would you like it if #msbuild (and dotnet build, etc) natively integrated with your CI/CD pipelines for integrated warning/error reporting and such? I've vibe-coded some stuff here that might be interesting to folks: github.com/dotnet/msbui...

It’s been a while since I wrote a blog post, and this one matters. Ever wished you could run multiple agents in parallel without wrecking your repo? I break down how Git worktrees + Copilot CLI make that happen for me.

Even if you are not into event driven systems, you should watch this talk by @noctovis.bsky.social

Thank you, @oskardudycz.bsky.social for making me aware of this.

This talk is a must-watch for people in the Event-Driven space. I saw @noctovis.bsky.social giving it live at this year's DDDEU, and I truly believe that she nailed the versioning topic 👇🙂

Geordi,

The comic shows two stick figure characters. The one on the left has messy hair and is holding a large chocolate bar while speaking excitedly. The character on the right has short curly hair and is standing with a neutral expression, looking at the other person. Above them, text reads: “Knowing is not enough, we must apply. Willing is not enough, we must do. Chocolate is not enough, we must eat.” The artwork is signed “heyokyay” in the bottom right corner.

Engineering,

The current ship-wide malfunctions might be related to an attachment I emailed Lieutenant Commander La Forge recently.

I have used many variants of the "temp directory that is cleanup up on dispose" testing pattern over the years.

I decided to finally bundle it in Verify

I am particularly happy with the "open in explorer and pause execution" debugging feature

#Java and #JVM folks, are you using the Outbox Pattern? If yes, then which tool are you using? It's a genuine question; I'd like to see if my anecdotal observations are real 🙂

Homebrewed? Debezium? Spring Modulith, other? 🤔

It's Patch Tuesday and ASP.NET Core has a doozy, with a CVSS score of 9.9, our highest ever. Let's examine why.

The bug enables http request smuggling, which on its own for ASP.NET Core would be nowhere near that high, but that's not how we rate things...
