New Aspire Bytes episode just dropped! 💫 @maddy.fm takes you on a tour of the Aspire dashboard - the control center for your local dev loop. 📺 www.youtube.com/watch?v=IeTa...

Hot on the heels of @aspire.dev releasing 13.6.0, we've shipped support in the Community Toolkit - github.com/CommunityToo...

Hello, Aspire 13.6 by @aspire.dev www.youtube.com/watch?v=mXPj... #aspnetcore #aspire

New home for the standalone @aspire.dev dashboard image! 📦 👋 Goodbye dotnet/aspire-dashboard 😍 Hello aspire/dashboard Update your image reference to mcr.microsoft.com/aspire/dashboard mcr.microsoft.com/artifact/mar... #Aspire #OpenTelemetry

I’ve been building a custom resource for @aspire.dev to learn more about some of the internals and make some content about it. I’m still not sure how more developers haven’t go in on this as the first choice for local dev experiences.

Aspire just lets you do stuff because it is all code. Here is what I've been working on. Add a local convex instance and dashboard to your distributed app. aspire.dev

🚨It's release day!!!🚨 Hello Aspire 13.6, and hello dashboard persistence👋🏻 One of the longest awaited Aspire features has now landed, along with plenty of other goodies. 🪶 Read the blog: devblogs.microsoft.com/aspire/whats... 📜 See the full What's New: aspire.dev/whats-new/as...

The Aspire 13.6 dashboard now uses Native AOT 💫 That means 66% faster median page-visible startup and no separately installed .NET runtime for the native dashboard executable. James walks through how the team got there: devblogs.microsoft.com/aspire/aspir...

My first son (11) has been on a vibe coding tear for the last couple of months. He's been making games on his web page kaicade.com. Play and give me some feedback for him!

It's time for Aspire 13.5 🎨💫 Run a fully interactive terminal inside the refreshed dashboard UI and deploy it to a Kubernetes cluster, all from a single TS or C# file! Blog: devblogs.microsoft.com/aspire/whats... Full What's New: aspire.dev/whats-new/as...

Some nice new features added to @aspire.dev 13.5! Check it out if you haven't already! Being able to run your fully distributed app locally with one command! Aspire gets better with every release (or daily if you like the thrill of running daily builds)

Why aren't more people talking about how @aspire.dev is literally the best debugging tool for a full developer experience. 🔥 Visit aspire.dev/get-started/... and find out. 🤓 #aiskills

New homepage, who dis? aspire.dev 🎨 💅

I was pretty sceptical with @aspire.dev when it first came out, but it's been worth its weight in gold for my team.

If you use Railway as your hosting provider and love a bit Aspire.dev then checkout my latest blog. I’ve build a set of NuGet packages to give first class aspire support for Railway. Publishing Aspire App to Railway intrepid-developer.com/blog/publish...

ICYMI: Aspire 13.5 has landed 💫 @maddy.fm shows you a couple of her favorite new features in our latest video! 🎥 www.youtube.com/watch?v=pEbo...

Mic still on?

In an AI-native world, human attention is a scarce resource. As @davidfowl.com pointed out, coding agents make software faster to produce, but they also make code harder to review, debug, and trust when the context disappears.

The hidden cost of agentic coding is code review. When producing code is trivial, human attention becomes a scarce resource. @davidfowl.com explains why review became the first bottleneck his team experienced as agents changed the scale of development.

Aspire 13.4 brings more of the local development loop into @VSCode.dev: AppHost CodeLens actions, live resource state, dashboard shortcuts, typed resource command prompts, TypeScript AppHost support, and multi-language debugging. devblogs.microsoft.com/aspire/aspir... #AspireDev

Beautiful

I needed a SQL Server database to test something. VS Code mssql extension could create a local sql server container for me but it does not work with podman. The wizard to create an Azure SQL Database was glitchy. In the end, best solution was to use aspire, in few minutes I had my database ready.

TypeScript devs no longer need to tangle with C# to use Aspire dev stack after Microsoft update

ICYMI: Catch the replay of the Aspire session by @maddy.fm and @davidfowl.com at #MSBuild! 💫 www.youtube.com/watch?v=ge5P...

Happy #msbuild Day 1! Come stop by the Aspire booth in the Expert Meetup area to say hi to @bethmassi.net @davidfowl.com and @maddy.fm (and grab a sticker!) 💫

Going LIVE NOW from #msbuild - @davidfowl.com and @maddy.fm showing a preview of their breakout session later today!! youtube.com/@aspiredotdev

Doing some test deployments via our AKS integration in #aspire 13.4 and just saw this content served up from our starter template app. Whatever place this weather is for I don't want to live there! 51c is rated as "Cool" :P

What is an apphost? A gentle introduction to @aspire.dev by @maddy.fm youtu.be/JLlnk3NrvRo

In this post, @davidfowl.com shows us how Aspire turns a development team's scattered tribal knowledge into an explicit, incrementally adoptable app model that humans, scripts, and AI agents can all use. devblogs.microsoft.com/aspire/dev-l... #AspireDev

Lots of people in the .NET ecosystem use Spectre Console (because it is awesome) and I am sure like others they are watching the development of Spectre TUI with interest. I wondered what would happen if I attached Spectre's IAnsiConsole as a workload to #hex1b. /cc @patriksvensson.se

@davidfowl.com nerd sniped me over the weekend with a bunch of bugs. One was a feature request to support select behavior on arbitrary areas of a #hex1b app. Here is an example of where it ended up:

I don't know what @maddy.fm @damianedwards.com and @davidfowl.com are going to do on #aspirifridays anymore. I just tried @maddy.fm 's /aspirify skill that is shipping in Aspire 13.3 and it just one shot migrated the Mealie app to use Aspire:

Git worktrees are the new hotness now that agents can work on parallel instances of your codebase. What they don’t solve is the port conflict problem, that’s where aspire run/start —isolated comes! By @james.newtonking.com devblogs.microsoft.com/aspire/aspir... #aspiredev @aspire.dev

Agents can write code all day, but running and iterating on it? Different story🫠 Aspire 13.2 adds structure and a real feedback loop for agents with code, not Markdown. @maddy.fm is here to share how Aspire gives your agent some bumpers 🎳 🔗 devblogs.microsoft.com/aspire/agent...

🎥 Now (re)playing on YouTube - the #AspireConf 2026 Keynote! Come meet the new Aspire with @damianedwards.com, @davidfowl.com, and @maddy.fm. youtu.be/6uGwVUWtWss #aspiredev #typescript #python #dotnet #githubcopilot #agenticdev

🎉 Starting soon! #AspireConf 2026 kicks off in just 1 hour 💫 Join us at 9AM PT to learn all the amazing new things you can do with Aspire. Join us LIVE: conf.aspire.dev?cid=aspireco... Follow the conversation: #AspireDev #AspireConf

L'estensione di David Fowler @davidfowl.com per Aspire è davvero interessante per chi deve fare deploy su Docker. Può semplificare notevolmente il processo di distribuzione su server remoti. github.com/davidfowl/as... #aspire #dotnet #docker

Just shipped an update to #hex1b today which adds a `WithDockerContainer` API to Hex1bTerminaBuilder. The idea is that you attach a running container to your terminal to help with test isolation. Works fairly well although not very visual. Was @davidfowl.com's idea. github.com/mitchdenny/h...

Aspire Conf - March 23, 2026 aspire.dev/aspireconf/ #aspire #dotnet

I built a thing: tallyai.money I wanted a fully offline way to track spending. Mint was fine, but categorizing transactions was always the worst part. There are really two problems: 1. Getting transaction data (hard) 2. Categorizing it the way you actually think about money (medium)

📣 It's happening! 📣 Come meet the new Aspire at #AspireConf on March 23. Join our livestream at 9am PT for a packed day of sessions for all developers, no matter your skill, language, or stack. Save the date: aspire.dev/aspireconf?c... #Python #TypeScript #JavaScript #dotnet #AI #AspireDev

if you aren’t subscribed to youtube.com/@aspiredotdev, now would be a good time, because @davidfowl.com is on vacation so @damianedwards.com and @maddymontaquila.net will be going rogue in a little bit 😈

I just shared with the rest of the @aspire.dev team a proof of concept for a TUI interface in the Aspire CLI. It is built with #Hex1b using a few features that I've been cooking over the weekend. This specific UX might not make it but it shows you what is possible.

After 7 years, my time at Microsoft has come to a close. I grew from a green dev into a bonafide engineer, shipped work I’m proud of, and learned what it takes to build software that lasts from amazing people. Taking a short breather then on to the next adventure! 🚀

shout out to @davidfowl.com who gave me the idea of tallyai.money but for blood sugar!
