How would you describe a "workspace" in Visual Studio in your own words?

🐞 Hard-to-repro bug? Let the agent cook. 🤖🧪

Visual Studio Debugger Agent’s new Test-Driven Investigation workflow creates/finds repro tests, debugs runtime behavior, validates fixes, and checks regressions. 🔍✅

Think the Debugger Agent is just for explaining exceptions? Think again. 👀
It can reproduce bugs, find root causes, suggest & validate fixes, analyze call stacks, debug failing tests, and more all with natural language.

Debugging isn’t just about fixing code; it’s about reducing uncertainty. We’re taking a massive leap toward solving that problem by introducing a new, upgraded, guided workflow within our existing Debugger Agent in Visual Studio.

Mark Downie lays it out for us... https://t.co/yhLj9KxtZp

Copilot in Visual Studio: Agents that Debug, Profile & Test

These aren’t just code‑gen bots — they find bugs from runtime behavior, surface perf issues, and build tests to block regressions.
A must‑see for C#, .NET & C++ devs.

@wstaelens Sorry you're running into this. Could you please file a feedback ticket with details about the memory usage and your setup? That’ll help us investigate what’s going on and figure out the root cause.
We’d really appreciate it.

@archiecoder Love this 🙌
Getting the agent to reason through the bug with you instead of jumping to conclusions was a big focus for us.
Thanks for trying it out and sharing 🙏

Stop Guessing, Start Fixing!

Meet the new Debugger Agent workflow in Visual Studio. ...not just a chatbot, but a real-time partner that reasons together with you.

Here's how to profile unit tests in Visual Studio and have Copilot help optimize your code https://t.co/8rsm2hFdy5

[Visual Studio Debugger @VS_Debugger]

Working with Copilot for debugging and profiling is now much easier with dedicated agents.

Just select the Debugger or Profiler Agent to get all the context-aware help you need to diagnose and optimize your application instantly.

[Visual Studio @VisualStudio]

🤖✨ Visual Studio just got a whole squad of agents — and they’re not your average “chatbot.”

🕵️‍♀️ Debugger Agent → reads your call stacks + diagnostics like a pro
⚡ Profiler Agent → hunts bottlenecks using real VS profiling data
🧪 Test Agent → generates tests that match YOUR project’s patterns
🛠️ Modernize Agent → upgrades .NET/C++ projects with awareness of your graph

And the best part?
🧩 You can build your own custom agents — wired into your repos, docs, APIs, design systems, and more.

Teams are already crafting:
• PR reviewers tied to their style guides
• Design‑system enforcers linked to Figma
• Planning agents that gather requirements before you write a line of code

Dive into how it all works + how to start building your own 👇

Got a slow LINQ query?

Now you can catch it and fix it while debugging.
Perf Tips + Profiler Agent in Visual Studio surface real runtime data as you step, and GitHub Copilot helps you optimize instantly. Currently supported in C# .NET.

#VS2026 Insiders

[Mads Kristensen @madskristensen]

A super easy way for me to optimize performance of my .NET application using my existing unit tests, the built-in profiler, and Copilot to tie it all together into a single click of a button.

Coming to Visual Studio 2026 very soon...

[Mads Kristensen @madskristensen]

You'll soon be able to run the Visual Studio profiler agent against your unit tests. I'm very excited for this feature

[Visual Studio Debugger @VS_Debugger]

@madskristensen @wstaelens Unfortunately, the Text Visualizer doesn't currently support strings with embedded null characters (\0) in the middle it essentially stops rendering at the first one.

[Mads Kristensen @madskristensen]

What features or extensions make you jump from Visual Studio to other IDEs and editors to perform certain tasks?

[Visual Studio Debugger @VS_Debugger]

Ever stared at a call stack thinking “okay… but why?”

Analyze Call Stack with Copilot is coming soon bringing instant clarity to sync & async debugging.
