5 Things VB6 and Legacy App Owners Should Take Away from MSBuild 2026

📣Don't miss this #MSBuild session: Using AI tools to teach old apps new tricks
Modernizing apps isn’t just rewriting code—it’s untangling dependencies, tracing data flows, and making changes without breaking production. In this session, you'll learn how to use agentic AI to take on the hardest parts of modernization: analyzing large codebases, mapping dependencies, planning upgrades, refactoring safely, while doing it all at scale. With GitHub Copilot modernization capabilities, you can move from legacy complexity to modernized apps in days, not months.

𝗗𝗲𝗹𝗲𝘁𝗶𝗻𝗴 𝟭,𝟱𝟬𝟬 𝗹𝗶𝗻𝗲𝘀 𝗼𝗳 𝗰𝗼𝗱𝗲 𝗺𝗮𝗿𝗸𝗲𝗱 𝗼𝗻𝗲 𝗼𝗳 𝗺𝘆 𝗯𝗲𝘀𝘁 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝘀 𝗮𝘀 𝗮 𝗹𝗼𝘄 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗲𝗿

But that deletion made the system measurably faster. It also reduced his line count, and what was funny was that the team was scored on the lines of code written. Management, none of whom were engineers, had decided that more code meant more productivity. So the engineer who made the system simpler looked lazy, while the ones padding it with copy-paste looked like stars.

That's 𝗚𝗼𝗼𝗱𝗵𝗮𝗿𝘁'𝘀 𝗟𝗮𝘄. Economist Charles Goodhart noticed it in monetary policy. Anthropologist Marilyn Strathern gave it the line everyone quotes: "When a measure becomes a target, it ceases to be a good measure."

A metric is a stand-in for the thing you actually care about: lines of code, tickets closed for quality. Reward the stand-in, and people optimize the stand-in until 𝗶𝘁 𝗾𝘂𝗶𝗲𝘁𝗹𝘆 𝘀𝘁𝗼𝗽𝘀 𝘁𝗿𝗮𝗰𝗸𝗶𝗻𝗴 𝘁𝗵𝗲 𝗿𝗲𝗮𝗹 𝘁𝗵𝗶𝗻𝗴. The number climbs. What it stood for walks away.

Same mistake, new units. Today, some teams measure AI tokens consumed (called tokemaxxing), where more counts as better, and a few include it directly in performance reviews. More tokens, more "work," better engineer. It's 𝗹𝗶𝗻𝗲𝘀 𝗼𝗳 𝗰𝗼𝗱𝗲 𝘄𝗶𝘁𝗵 𝗮 𝗳𝗿𝗲𝘀𝗵 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱.

It happens anywhere a number gets a bonus attached. Reward coverage percentage, and you get trivial tests that assert nothing, while the hard integration tests stay unwritten. Reward tickets closed, and one bug becomes five. The metric goes green. Quality doesn't move.

Before you attach a reward to a number, ask one question: could gaming it leave you worse off than measuring nothing at all? If yes, you're 𝗼𝗻𝗲 𝗽𝗼𝗹𝗶𝗰𝘆 𝗮𝘄𝗮𝘆 𝗳𝗿𝗼𝗺 𝗯𝗿𝗲𝗲𝗱𝗶𝗻𝗴 𝗰𝗼𝗯𝗿𝗮𝘀.

Sounds like MS learned from @kevinolearytv - in a good way. #msbuild

[DeeDee Walsh ⛷🎿❄️ @ddskier]

#MSBuild opens today and agents are becoming first-class runtime citizens. But let’s be real: you can’t wrap a 25-year-old monolithic VB6 app in an API and call it a day. If your core logic is invisible to AI, it’s time to move to .NET & Blazor.

How AI coding agents actually use your technology - Microsoft for Developers
You ship an SDK, a CLI, an API, and developers use it. Now AI coding agents use it too, except they use it differently than humans do. Most of the time

Just a few more days until #MSBuild -
GitHub Copilot in Visual Studio: Agents That Debug, Profile & Test

Every IDE can generate code now — but VS goes way further.
These agents root‑cause bugs using live runtime data, spot perf bottlenecks, recommend targeted fixes, and build test coverage to stop regressions before they ship.
Enterprise C#, .NET & C++ devs: this one’s for you.

AI code assistants produce insecure code at twice the rate of humans. Veracode found flaws 45% of the time; CodeRabbit says XSS is 2.74x more likely. Greenfield "vibe coding" leaks an API key which is bad, but recoverable. Apply that math to a 25-year-old legacy app rewrite? Disaster.
In our ongoing series inspired by #MSBuild, we share our advice on vibe coding legacy apps: https://t.co/oVzQJSUKoR

Great new doc published for any agent builders who are also using @github Copilot CLI / App, Claude Code, or any other coding agent. Now you can add skills to help your coding agent be an expert in deploying to Microsoft Foundry! https://t.co/gsMOXwNG7U 🥳

I like the direction Microsoft Foundry is taking with Model Router. In production AI apps every request does not need the biggest or most expensive model.

Routing based on cost, latency, quality, and complexity is a much better architecture pattern. https://t.co/6LKmSqCTQg
