Debugging, but Without the Drama (A Visual Studio 2026 Story)

Harshada Hole

It starts the way these things always start.ย 

A red build. A failing test. And that quiet, sinking feeling ofย โ€œThis worked yesterday.โ€ย 

Meet Sam. Samโ€™s not a junior, not a rockstar,ย just a solid developerย whoโ€™sย shipped enough code to know that bugsย donโ€™tย care how confident you feel on Monday morning.ย 

That test failure does not offer much help at all. There are no clear steps to reproduce the issue.ย The exception message seems familiar in a vague way.ย But it does not prove useful right then.ย Out of habit Sam hits F5.ย He notices something small yetย pretty importantย about it.ย 

The debugger launches faster than before.ย No long pause, no breaking his flow. Sam gets straight into debugging, and that small improvement already feels like a win.ย 

The Exception Knows More Than It Used Toย 

The app crashes. Sam opens theย exceptionย details. Normally,ย heโ€™dย read the error message, scroll through the stack trace, which shows the chain of function calls that led to the crash and start guessing what went wrong.ย 

This time, things feel different. Exception Assistance โ€˜s Copilot analysis looked at the whole repository, not just the file in front of Sam. It checks past bugs, old pull requests, and even fixes from months ago. It notices a similar error that happened after a validation tweak, flags the code paths that might have been hit, and points to places where that odd value could have slipped in.ย 

If Sam wants a different angle, he canย pickย anyย model in Copilotย Chat to analyze theย exceptionย the way that fits the problem. And for trickier, nested, or chained errors, Copilot may decide it needs more context and offer to dig deeper.ย ย Sam can continue with the deeper analysis to get a more context-driven,ย accurateย understanding of what went wrong, without losing control of the investigationย 

What used to take hours now feels like a conversation with a teammate who knows the history of your code and points you exactly where you need to look.ย

Inline Values: When If-Statements Stop Lying and Values Appear Where You Need Themย 

Sam steps through the code and lands on a conditional thatย shouldย beย true butย is now showingย false.ย 

Normally,ย youโ€™dย hover over every variable, checking them one by oneย butย now? The result is right there. Inlineย in editor.ย The condition shows how it was evaluated.

Sam hovers and chooses Analyze withย Copilot.ย Insteadย of just seeing โ€œfalse,โ€ Copilot breaks the condition apartย sub-expression by subย expressionย showingย exactlyย which part failed and how it affected the outcome.ย No stepping. No breakpoint.ย Just reasoning where the decision happened.ย ย 

As Sam moves on, he notices something else that clicks:ย 

  • Method parameters? Inline.ย 
  • Loop variables? Inline.ย 
  • Return values?ย Inline, where theyโ€™reย used, not buried inside a function call.

One wayย keeps returning a value that feels wrong.ย Samย doesnโ€™tย step into it.ย Doesnโ€™tย add watches. Heย just hovers, asks Copilot to analyze the value, and instantly sees an explanation grounded in runtime behaviorย andย the surrounding code.ย 

Itย doesnโ€™tย replace DataTips orย visualizers;ย theyโ€™reย stillย there when Sam needs toย dig deeper.ย But most of the time, the answer heโ€™s looking for is already right in front of him.ย

When a Test Fails, and Youย Donโ€™tย Debug Aloneย 

Later that day, another testย failed. Differentย feature. Same frustration. Sam right-clicks the test and selectsย Debug with Copilot.ย 

Theย Debugger Agentย takes over.ย It looks at the test, its code, and recent changes.ย Then it makes a guess, applies a fix, runs the test, adjusts, and tries again.ย Sam watches.ย Not hands-off, but without the usualย busy work.ย Whenย itโ€™sย done,ย thereโ€™sย a clear summary of whatย has changedย and why. Sam reviews it, nods, and commits.ย 

Thisย isnโ€™tย giving up control. Itโ€™sย cutting out theย repetitive stuffย so Sam can focus on the important decisions.ย

The Calm at the End of Debuggingย 

By the end of the day, Sam notices something important.ย 

The bugsย werenโ€™tย easy. The codeย wasnโ€™tย simple. Butย understandย them? That came faster.ย 

Visual Studio 2026ย doesnโ€™tย make debugging magic. It makes it feel like aย conversationย between Sam, his code, his history, and tools that get the context.ย By the end of the day, Sam closes the debugger feeling focused, not worn down.ย ย 

Theseย improvements in Visual Studio 2026 are the first steps toward a smoother, calmer, more intuitive debugging experience, less time guessing, and moreย time understanding. ย Thereโ€™s a lot more coming, and your feedback is crucial. Tell us what works, what doesnโ€™t, and where debugging still trips you up.ย 

Happy Debugging.ย ๐Ÿ™‚ย

    Harshada mam,
    Eventually! Microsoft team has resolved the debugging drama without any wasting time in Microsoft Visual studio 2026.
    Thanks Your Team.

    I wish debugging improvements were made that didn’t involve AI.

      Exactly! I am of the same view.

    It is great to have more tools to help debug issues. However as a Windows app developer I can say the biggest challenge I face is that WinUI3 does not provide useful information in the exceptions. Frequently apps crash hard and the error is “unspecified” making it impossible for a human or LLM to understand. As LLMs get more integrated it underlying issues with frameworks will become more apparent. Hopefully that means they will receive more attention and funding to fix.

    Is support for CoPilot unit test debugging for C++ code on the roadmap? Currently it works only for C#).

    We’ve invested heavily in the MS Test framework for our C++ code, and it’s frustrating that while CoPilot can author C++ tests, it cannot interact with the Test Explorer to run the tests or debug them.
