Visual Studio Debugger

@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.

grrrr DevHub.exe stop eating memory @VS_Debugger 🤬🤬

In today's Visual Studio Toolbox highlight, Marco shows us how Visual Studio has a new, upgraded, guided workflow within the existing Debugger Agent to help you fix issues. Check it out: buff.ly/hSDYWpX

Check out the latest Visual Studio Toolbox episode Watch as @mpeyrotc from the Debugger team explains the Debugger Agent. Learn how to use the guided workflow to navigate from bug report to verified fix with total precision in runtime. #VisualStudio2026 youtu.be/FdwnVdIHEPM?si…

@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 🙏

I just did my very first debugging session with the new Developer Agent @VS_Debugger and wow, oh wow 🤯 I started with a screenshot and a vague description of where the bug could be. The agent asked me to reproduce the bug 4 times. It made assumptions and put breakpoints along the way. It eventually understood the whole scenario and gave me the fix. I would probably have spent an entire day without this. Thank you @VisualStudio 🙏

Here's how to profile unit tests in Visual Studio and have Copilot help optimize your code youtu.be/9zcg206kEoI?si…

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.

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

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...

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

@mkristensen @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.

@wstaelens @VS_Debugger

@mkristensen text visualiser shows "\0\0..." over my "ref allText" parameter but in the dialog (when clicking View) nothing to see or to select... any improvement to make here? #VS2026

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

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.

Finding the real issue often means tracing deep call chains. From Live! 360 Orlando, see how GitHub Copilot analyzes context, builds hypotheses, and helps uncover root causes 🧩 Watch to learn more: youtu.be/iFjQghRbJUw

@mkristensen @johnzabroski @HarshadaHC looks like you have some 3rd-party extensions installed, and we can see inline variables coming from it. We suspect this may be specific to your setup, as we haven’t received any other reports of this issue. Could you please file a feedback ticket so we can take a closer look?

@johnzabroski @HarshadaHC @VS_Debugger

@mkristensen We have noticed that since Visual Studio 17.14.21 or 22, data tips no longer really work. It doesn't depend on whether I have "Keep expanded data tips open until clicked away" or "Enable property evaluation and other implicit function calls" is enabled/disabled.

@Sam75614812 @mkristensen The profiler agent can help here too. Even if you don’t know anything about benchmarking, that’s completely fine. It can automatically add a new benchmark suite and generate benchmarks for you if your project doesn’t already have them. See this example youtu.be/u8kPpwvI1AI?si…

@mkristensen Could you make a YouTube video showing this process? I’d like to see it in practice on real code. I’m not even sure how you to even begin to benchmark UI code like you’re doing.

I’ve been having a blast adding benchmarks to my Visual Studio extensions and letting the Profiler Agent work its magic. The optimizations are incredible. Stuff I’d never pull off on my own. It often boosts performance by 5x and slashes allocations.

Debugging, minus the drama. In #VisualStudio2026, #Copilot helps with exception insights from your repo, honest inline values, and condition analysis that shows exactly what failed—so you move faster when tests flake. Get details, real examples, and quick walkthroughs: msft.it/6011tmf4W

@mkristensen @MichaelJAkin @timheuer Sorry you had to downgrade, that’s frustrating. What wasn’t working when you tried to debug your Blazor app? We’d like to get this fixed.

@MichaelJAkin Yikes! Let's add @VS_Debugger and @timheuer

We’ve been dogfooding the Profiler Agent in Visual Studio, and today it shaved off 800K allocations during VS startup, saving about 50MB of heap right out of the gate.
