An experiment in Aspire dashboard extensibility 📊
I recorded a quick demo showing how custom pages could work in the dashboard. Watch to the end. It starts simple and ends crazy 🚀
Note: This is an experiment. No commitments (yet...)

I have willingly added an iframe to a web app, and I'm happy with the outcome.
Note: my account is not hacked. I know this goes against all prior evidence. Feel free to contact me offline for a welfare check.

Second for second, @tylercowen packs more substance into a talk than anyone I'm aware of. This is a clear, non-hysterical, and somewhat soothing discussion of our AI future.

Aspire 13.4 dashboard and CLI features, day 4
The dashboard adds an AI Agents button that opens a guide to using Aspire with agents.
Adoption pipeline:
📊 Standalone dashboard (hook)
🤖 Aspire CLI for agents
🛠️ Aspirify skill → Aspire AppHost
🚀 Adopt C# (best language 💪)

Telemetry filtering got a major upgrade in the CLI and dashboard HTTP APIs. Find matching telemetry faster with:
🔍 Full-text search
🏷️ Attribute filters
⚖️ Comparison operators
🚫 Negation
Perfect for humans and agents 🤖

The console logs page now shows a helpful message when no logs are found instead of a blank screen 🔳
A small but important quality-of-life improvement:
Did Aspire break (!) or are there simply no logs yet? Now you know 🤓

.NET bet on OpenTelemetry early. It was the right one 💪

This was a pretty incredible journey. I rememeber when .NET had its own version of distributed tracing (didn't everyone before otel??).
Now it's a no brainer, if you aren't using otel for tracing you should be.

I want AI to automatically fix builds and tests, so I ask it to run them. But it's wasteful sending the whole context window for "run tests".
Coding assistants need some sort of gesture to run build/test steps and only involve AI on failure.

We added error reporting to the Aspire dashboard back in 9.3, over a year ago.
What's wild is the 9.3 userbase is now tiny (please upgrade 🙏), yet it generates the most error reports.
Telemetry has been invaluable. We've used it to squash errors in every release since 🔨📊

Aspire 13.3 dashboard and CLI features, day 7:
Aspire CLI success ticks were purple. Or black. Or green if you're on Win10. Or green if your terminal doesn't support emoji and you saw a unicode tick: ✓
It's complicated.
Now they're consistently green ✅
Apr 22
The cross_mark emoji is red (❌)
But the check_mark emoji is black/purple (✔️)
And the only green check is check_markbutton (✅)
How did we end up here?
