#CSAdvent post 1 for December 18, 2025! "From Spec to Santa: My C#‑Powered Christmas Story Generator Experiment" by @techwatching.bsky.social techwatching.dev/posts/christ... #dotnet #csharp

And here is my C# Advent post 👉 techwatching.dev/posts/christ... Or how I created a Christmas story generator using GitHub Spec Kit. @csadvent.christmas #aspire #dotnet #github

Aspire 13.1 new dashboard features, day 1: Aspire's Gen AI Visualizer adds a UI for tool definitions. You can now view detailed information about tools included in an AI request.

I had fun this week-end with GitHub Spec Kit. I started from an @aspire.dev Blazor+Minimal API template and built a Christmas Story generator for my almost 5-year-old daughter. First time for me with Microsoft Agent Framework and Blazor. GitHub Copilot did a good job. Aspire MCP is awesome #github

Background agents in latest vscode version seem awesome. Having everything built-in to delegate tasks to agents that work locally, autonomously, and potentially in an isolated context is going to be game changer. code.visualstudio.com/docs/copilot... #vscode #githubcopilot

Watching AspiriFriday replay featuring @scott.hanselman.com @maddymontaquila.net @damianedwards.com and @davidfowl.com is both highly educational and incredibly entertaining. On one side so many small learnings (tools, way of thinking, tips, good practices, etc). On the other side, just pure fun 😊

@acolombiadev.bsky.social nice video about GitHub Copilot Spaces! Usage with Copilot Agent is very interesting. However for the MCP, in its current state Copilot can't use the content of a space so it's useless. Are other tools currently being developed for this MCP? www.youtube.com/watch?v=noVd...

Today, AI didn’t solve my coding issue. I tried Gemini Pro 3, Claude Opus 4.5, and GPT‑5.1 Codex. None helped, even with full context from my IDE and docs. The problem wasn’t complex—the solution was simple once found 😁. The issue was that the AI gave wrong answers, not the right one 🤣.

@captainsafia.com I've discovered your blog recently and I love reading your articles, especially the ones about Aspire. Great job. It seems Aspire is starting to overlap with some tools like Nuke, Cake, or Pulumi. I was wondering, is the plan to integrate with them or be an alternative to them?

After getting used to Swagger UI, using Scalar as the OpenAPI UI feels like a fresh breath of air. Anyway, I'm still using mostly http files in my IDE or Bruno to send my requests, but it's always nice to see something different. #dotnet

I've been trying to use GitHub Copilot Modernize feature to upgrade my application to .NET 10. The plan is nice, but the execution it depends, it can take time and make some format (or worse) issues in your csproj. Setting TargetFramework in Directory.Build.props would have help me. #dotnet

The Aspire 13 has just been released alongside .NET 10, offering support for Python and JavaScript as first-class citizens and many other improvements 👉 aspire.dev/whats-new/as.... Don't forget to subscribe to @aspire.dev, let's reach 1000 followers for Aspire on Bluesky. #dotnetconf

🚀 .NET Conf kicks off today in 30 minutes with the launch of #dotNET10 and updates about #VisualStudio2026! Join at dotnetconf.net and don't forget to follow @aspire.dev (let's hit the 1000 followers for aspire on Bluesky by the end of the week!) #dotnet

So few followers, it seems developers did not realize Aspire is on Bluesky. Developers make this number up. I'm sure we can reach 1000 followers by the end of the week. Share for more reach! @aspire.dev #dotnet #aspire #developer

The real ones know what it means when JNK starts tweeting dashboard features.... #aspire13 #comingsoon

@lostinbrittany.bsky.social Your talk at @bdxio.bsky.social was awesome!It really resonated with me. I can't wait for the series of articles, I've seen you write the first one. Any RSS feed I could subscribe to for lostinbrittany.dev?

Quick way to remove of bunch of old stacks in Pulumi using Nushell. #nushell #pulumi

Started using GitHub Copilot to update Azure DevOps work items — not for laziness, but for flow. When I’m deep in design, I stay in my IDE. Copilot + MCP Server = context, updates, no tab-switching. What felt like a gimmick is now part of my daily dev stack. Not perfect, but powerful.

Just announced and already in GitHub Copilot in preview. Hello Claude Haiku 4.5. Smaller model but supposed to be almost as good as bigger ones to code. Looks fast and cost one-third of Claude Sonnet 4.5. Interesting model to test. #GitHubCopilot #Anthropic

Brainstorming with GitHub Copilot CLI and the relevant MCP Server (in this context Microsoft Docs MCP) can be very useful. Generating code is far from being the only usage of using AI in IT. #GithubCopilot #MicrosoftDocs #Azure

You don't realize how great .NET Core is until you find yourself having to work with .NET Framework again. I have no doubt that you can do great things with the .NET Framework, but .NET Core makes your life easier and encourages you to do things right. #dotnet

Very interesting read 👉 engineering.usemotion.com/moving-off-o...

Rendez-vous lundi 🤩

@den.dev a GitHub Spec Kit question for you 👉 is constitution file a good place to tell AI to use specific MCP servers for some tasks. I have trouble sometimes to know if things should go in the constitution or be asked in the /plan.

💬 Unpopular opinion: most CLIs should have an option to output command results as JSON (or other structured format). It would make things so easy to query (using Nushell, PowerShell, jq, etc). 🔧 Some CLIs do, azure cli for instance, but many don't bother.

When you start doing something in your terminal And you decide it's time to "quickly" add proper completions to your shell But your shell needs an update, so you do it The update breaks your config, so you fix it ... Carapace now provides me nice completions! What did I wanted to do again?

I love this new #GitHubCopilot update for JetBrains IDEs. Next Edit Suggestion was something I had been waiting for for a long time.

I'm writing more and more of "How to" notes. Current one: How to customize your shell prompt?

TIL I learn I could use aliases for my notes in @obsidian.md. Basic feature but I completely missed that and it is very useful to make to notes that are not named with the proper name because of some characters being forbidden. (.NET -> dotnet, C# -> C Sharp for instance).

Taking notes: 📆 Before ➡️ Bookmark blog posts, videos and documentation pages about some tech, eventually write a few bullet points and a code sample 🕰️Now ➡️ Write my current understanding of something, the usage I have of it, my choices, and the why 💭 Tomorrow ➡️ Keep learning, improve my notes

I did an overhaul of the Awesome Copilot README to make it easier to install the prompts, instructions, and chat modes to VS Code - there are nice big buttons to click! github.com/github/aweso...

TIL I should have checked the default duration for a cache entry instead of trying to figure out why my code using hybrid cache/fusion cache seemed to failed storing entries in the cache. Great library by the way @jodydonetti.bsky.social, I'm only starting using Fusion Cache but it's promising.

Introducing Bases, a new core plugin that lets you turn any set of notes into a powerful database. Now available to everyone with Obsidian 1.9!

At a time when everyone swears by their favorite AI, when many no longer see the point in writing blog posts, I take notes... Notes as I go along, on just about everything, what I learn, the tools I use (why, how, alternatives). Will it be useful? We'll see.

I just released FusionCache v2.4.0 🥳 It includes: 🏷️ explicit stale tags handling Ⓜ️ better HybridCache options mapping 🐞 some bugs fixed 📕 better docs github.com/ZiggyCreatur...
