Introducing VBUC 11: Smarter Shared File Handling, Cleaner Code, and Performance Improvements

We’re thrilled to announce the latest release of our AI modernization engine: Visual Basic Upgrade Companion (VBUC) 11. If you’re navigating a large-scale VB6 to .NET migration, this update is for you. Think: smarter handling of shared code, cleaner outputs, and performance gains your developers will actually notice.

Let’s unpack what’s new and why it matters.

First, a Quick Refresher: What’s VBUC?

VBUC is not your average migration tool. It’s a deterministic AI engine that automates the conversion of Visual Basic 6.0 apps into modern .NET (C# or VB.NET) applications. Built for enterprises, VBUC turns legacy code into clean, idiomatic .NET code with traceability, precision, and auditability, the stuff enterprise compliance teams dream about.

Unlike black-box generative AI models, VBUC is predictable by design: the same input always produces the same output. That’s huge when you're migrating revenue-critical or regulated systems.

💡 So Why Do Teams Choose VBUC?

Because modernization is hard and risky. VBUC reduces that risk by:

• Eliminating the need for brittle, time-consuming manual rewrites
  
  
• Generating structured, maintainable .NET code
  
  
• Supporting massive, multi-project systems
  
  
• Reducing technical debt at scale
  
  
• Keeping transformation outcomes explainable and enterprise-ready
  
  

VBUC is trusted by global ISVs, healthcare systems, financial institutions, and anyone else with old but mission-critical VB6 code they can’t afford to break.

What’s New in VBUC 11.0.3?

🔄 Smarter Shared File Handling

One of the biggest improvements in 11.0.3? A total revamp of how VBUC handles shared files across multiple projects.

Shared files in legacy apps are… a thing. Historically, VBUC would duplicate logic across projects to keep things compiling, but that bloated your output and made long-term maintenance a headache.

Now? We’ve reengineered our shared file generation using compilation directives, allowing multiple versions of logic to live in harmony within the same file. Think of it as modular logic with a brain.

Technical Benefits:

• Drastically reduces redundant code across projects
  
  
• Promotes cleaner, centralized source structures
  
  
• Improves consistency across the entire application landscape
  
  
• Simplifies future updates, debugging, and testing
  
  

Business Payoff:

• Less code = less testing, less debugging, and less maintenance
  
  
• Fewer errors from mismatched project logic
  
  
• Shorter modernization timelines
  
  
• A better foundation for future AI-assisted enhancements
  
  

🛠 Performance Improvements and Fixes

VBUC 11 also includes some meaningful tune-ups:

• Smarter discard handling, leading to better runtime performance
  
  
• Expanded support for interpolated strings and True DBGrid
  
  
• Improvements in EditLib for better control mapping
  
  

In short, your modernized app runs faster, looks better, and behaves more like a native .NET application.

Why It Matters

VBUC isn’t just about moving code from point A to point B. It’s about modernizing with confidence. With VBUC 11, you get:

• Better output quality
  
  
• Shorter migration timelines
  
  
• Safer outcomes for large, critical systems
  
  
• A future-ready foundation for AI initiatives
  
  

We’re modernizing not just code, but your team’s entire approach to transformation.
