Do you trust AI-generated software to meet your development needs compared to traditional manual coding?

Userware has released XAML.io v0.9, a preview platform that allows developers to create .NET applications using text prompts within a browser. The AI agent generates functional C# and XAML files that are exportable as standard .NET 10 solutions.

Why it matters

The tool aims to lower the barrier to entry for .NET development while providing a path for migrating legacy Windows Presentation Foundation applications to the web. It is designed to handle complex migration tasks that typical automated conversion tools cannot resolve.

The AI agent operates by managing project files, compiling code, and iteratively debugging errors until completion. In testing, the tool generated 3,500 lines of code for a Paint application in 42 minutes.

The players

Userware

A software company focused on development tools and migration services with a decade-long track record in the .NET ecosystem.

The details

XAML.io v0.9 provides an integrated environment where developers switch between prompt-driven generation, manual source code editing, and visual design tools. The system compiles applications that can be published to the web or targeted for Windows, macOS, and Linux. For migrations, Userware leverages 13 years of experience, having previously moved 10 million lines of front-end code for customers.

The Tech Race

XAML.io enters the competitive field of AI-assisted software development by specifically targeting the .NET 10 ecosystem. It differentiates itself from generic code generators by focusing on complex migration tasks and maintaining compatibility with established Windows Presentation Foundation frameworks.

Developers can access XAML.io via free accounts that include cloud saving and a $5 monthly AI usage budget. A Pro tier is also available for $20 per month, providing a $20 AI usage budget, though Userware stipulates that customer code is not used for training their AI models.

The takeaway

The platform demonstrates a shift toward browser-based, AI-driven scaffolding for desktop application architectures. Developers should monitor future updates to the v0.9 preview to see how the system handles increasingly complex enterprise project structures.
