TuiVision: Modernizing Classic Turbo Vision with C#/.NET 10 & AI-Assisted Workflows

TuiVision is an educational open-source project that modernizes the classic Turbo Vision TUI framework using C#/.NET 10. It integrates Agentic-AI and Specification-Driven Development (SDD) workflows, aiming to demonstrate how classic tech concepts can be revitalized with modern tools. Key focuses include accessibility, inclusive design, and providing learning opportunities for IT professionals and developers.

Section 02

Background: The Revival of Classic TUI Technology

Turbo Vision, developed by Borland in the 1990s for Turbo Pascal/C++, was a popular TUI framework for DOS apps. While it faded with GUI's rise, TUI remains valuable for server tools, embedded systems, and remote terminals (low resource, keyboard-friendly). TuiVision was born to modernize Turbo Vision's core concepts (not just a direct copy) using C#/.NET10, breathing new life into the classic framework.

Section 03

Technical Architecture: .NET10 & Retained Core Concepts

TuiVision uses C#/.NET10 for its cross-platform capabilities, performance improvements, and modern tooling (VS/VS Code). It retains Turbo Vision's core design: event-driven model, view-window hierarchy, and dialog system—proving the lasting value of these classic patterns. The net10.0 target framework leverages latest runtime optimizations, offering better type safety and memory management than original Pascal/asm implementations.

Section 04

Innovative Workflow: Agentic-AI + Specification-Driven Development

TuiVision adopts an SDD workflow via speckit CLI: create specs (spec.md), answer clarifications, plan (plan.md), generate tasks (tasks.md), then implement. Agentic-AI assists in generating docs, suggesting implementations, and supporting multi-Mac collaboration (MacBook Air M2 & Mac Mini M4 Pro via GitHub CLI/Codex). This workflow is ideal for IT training, teaching modern SE practices.

Section 05

Accessibility & Inclusivity: A Priority in Design

TuiVision ensures WCAG 2.2 AA compliance: clear heading hierarchy (h1→h2→h3), image alt text, descriptive links, code language labels, table headers, and no color-only info. Automation checks use Playwright + axe-core; manual checks with Lynx browser. Bilingual support (German/English) at CEFR-B2 level ensures global accessibility.

Section 06

Educational Value & Project Governance

Learning goals: TUI programming (screen buffers, event loops), .NET10 features (async, cross-platform), SE practices (SDD, AI-assisted dev, accessibility), and open-source collaboration (GitHub Actions CI/CD, XML docs, code reviews). Governance: MIT license, copyright respect; QA includes compliance scripts, CI/CD, doc sync, and pre-push hooks.

Section 07

Insights & Conclusion

TuiVision shows classic tech's enduring relevance (its design patterns are still used in modern GUI frameworks). It sets a high bar for educational projects (accessibility, bilingual docs, automation). The AI-Agent + SDD workflow hints at future dev collaboration models. For learners of TUI, .NET10, or modern SE practices, TuiVision is a valuable resource and model.
