Uno Platform today announced Uno Platform Studio 2.0, a major AI-based update to its cross-platform .NET coding solution.
“Uno Platform Studio 2.0 is the first and only way to build cross-platform .NET applications, visually and with AI, with full human-in-the-loop control,” the Uno Platform team writes in the announcement post. “With today’s Uno Platform Studio 2.0 launch, we’re shipping one new feature and two new toolchains in the Studio productivity suite, and current subscribers get them automatically.”
Uno Platform released the first version of Uno Platform Studio in November 2024, bringing a next-generation visual designer, Hot Reload, and Hot Design capabilities to developers who wish to create cross-platform .NET apps. But with the 2.0 release, Uno Platform Studio is jumping into agentic coding capabilities with a Hot Design Agent that builds app UIs in the real-time while you work and two MCPs, Uno Platform MCP for accurate, stack-aware guidance, and Uno Platform App MCP that helps the agent interact with your app directly.
The Uno Hot Design Agent helps you implement visual changes to your app in the designer or while it’s running. It understands the visual structure of your app using the runtime context exposed by the App MCP. And it can suggest UI updates, align layouts, apply styles, and perform other UI-related tasks with previews before committing any changes. In other words, where Hot Design provides a live visual UI editor, the agent lets you collaborate on the UI with AI in real—time.
The Uno Platform MCP is grounded in the official Uno documentation, APIs, and best practices, providing that information to AI agents and developers so you get real-time assistance as you code. And the App MCP is a local runtime service that allows AI agents to interact with live Uno apps running across Windows, WebAssembly, macOS, iOS, Android, and Linux. This includes app state, live inspection, and workflows like automated UI testing, intelligent debugging, adaptive exploration, and telemetry-driven optimization, Uno Platform says.
Uno Platform says there are several main use cases for these new features, among them:
New app creation. You can create a new app from scratch using just a prompt.
Create a UI using just a screenshot. Uno Platform Studio can turn a screenshot into the UI for your app using a simple prompt.
Modernize an existing app. You can feed Uno Platform a WPF, Windows Forms, or Xamarin Forms app and turn it into a modern, cross-platform app. Interestingly, Uno did this with my original WPF version of .NETpad, and Uno Platform Studio transformed it into a modern, cross-platform app in just 3 minutes.
Create an app using a Figma design. Here, you feed a link to a Figma design to Uno Platform Studio and it will use the Figma MCP to transform it into a running Uno app.
You can learn more about Uno Platform Studio on the Uno Platform website, and the Hot Design Agent and MCP servers are now available in all editions, with no limits during the launch. And Uno Platform CTO Jérôme Laban will be presenting at this week’s .NET Conf 2025 on Thursday, November 13 at 1:00 pm ET if you want to see a live demo. I’m hoping that my app will make a guest appearance.
