2025 was a transformational year for both the broader software development industry and Uno Platform. We are pleased with how we addressed several long-standing gaps in the .NET ecosystem while also staying on top of AI trends—and, in doing so, helped redefine what modern cross-platform .NET development means.
We grew our team, grew the community and adoption of Uno Platform – lets revisit the highlights.

Uno Platform 6.0 and Uno Platform Studio GA
Nearly seven years after unveiling Uno Platform, we shipped what we called our “biggest release ever.” Uno Platform 6.0 wasn’t just an incremental update, it was a complete re-engineering of the platform and the general availability of Uno Platform Studio which delivered a long-requested Visual Designer for cross-platform .NET development!
Unified Skia Rendering Engine
The headline feature was our new unified Skia rendering engine. Previously, Uno Platform used different rendering approaches across platforms. With 6.0, we unified everything under Skia — delivering consistent, hardware-accelerated rendering across iOS, Android, WebAssembly, Windows, macOS, and Linux.
Uno Platform Studio Goes GA
After over a year in development, we declared Uno Platform Studio generally available. The suite transforms how .NET developers build cross-platform apps.
Hot Design
Runtime visual designer — pause your app, edit the UI, see changes instantly.
Hot Reload
Instant XAML and C# changes with visual confirmation.
Design-to-Code
Generate production-ready XAML from Figma designs.
New Controls
In addition we released:
- MediaPlayerElement — Cross-platform video playback using platform-specific backends
- WebView2 — Chromium-based web content embedding with JavaScript interop
Hot Summer - Rapid Iteration and Funding
July : Uno Platform 6.1
Two months after 6.0, we shipped Uno Platform 6.1 with over 300 pull requests merged. The highlight was CommandBarFlyout a floating contextual toolbar with support for keyboard accelerators and the StandardUICommand API.
Hot Design received significant updates including a new Thickness Editor for visual margin/padding adjustments and improved property toolbox indicators.
August 12: $3.5M CAD Seed Round
💰 Funding Milestone
We completed our seed round — $3.5 million CAD (approximately $2.54M USD) — bringing total investment to $6.5M CAD. The round was co-led by AQC Capital and Desjardins Capital, with participation from Scott Hanselman, Microsoft's VP of Developer Community.
August 26: Uno Platform 6.2
Just five weeks after 6.1, Uno Platform 6.2 landed with nearly 100 community-reported issues closed. Key improvements included the SKCanvasElement API for unified Skia/native rendering and WebView2 lifecycle alignment with WinUI.
Microsoft Collaboration, .NET 10, and AI
October 9: Uno Platform 6.3
Uno Platform 6.3 closed over 128 issues and positioned us for the upcoming .NET 10 and Visual Studio 2026 releases.
- .NET 10 RC1 support — Target .NET 10 directly from the project wizard
- Visual Studio 2026 ready — Full support for the new
.slnxformat - WebAssembly breakthrough — Image decoding moved to WebWorkers for smoother scrolling
- TabView refinements — New sizing modes and non-closable tabs
October 14: Microsoft .NET Team Collaboration
This was a milestone we’d been building toward for years. We announced an official technology collaboration with Microsoft’s .NET team. We were honored by keynote mention alongside the likes of RedHat, AMD, Canonical and others.
.NET for Android
Six weeks of joint engineering for Android 16 (API-36.1) support.
SkiaSharp
Co-maintaining the graphics engine that powers Uno Platform.
WASM Multithreading
Contributing to .NET runtime for this highly-requested feature.
November 11: The AI Release
Timed with .NET Conf 2025, we shipped Uno Platform 6.4 and Studio 2.0 — bringing agentic development to cross-platform .NET. Our CTO Jerome Laban had a dedicated session where he officially unveiled Uno Platform Studio 2.0 and demonstrated its AI capabilities – from modernization, app creation from prompt or design, and more.
Day-0 .NET 10 and Visual Studio 2026
Uno Platform has supported new .NET versions on launch day for years, and .NET 10 was no exception.
Uno Platform Studio 2.0: Agentic Development
Studio 2.0 introduces three AI-powered capabilities that transform how you build apps:
🤖 Hot Design Agent
The first agentic visual designer for cross-platform .NET. An AI assistant embedded in the visual designer that can read layout hierarchies, suggest UI updates, reorganize components, and apply styles — all within a running app.
Uno Platform MCP
Model Context Protocol server connecting AI agents to our complete knowledge base — documentation, APIs, and best practices.
App MCP
Runtime service exposing visual tree, data context, and control properties to AI agents across all platforms.
December 9: Uno Platform Studio - official Webinar & Celebration
We closed off the year with a dedicated webinar for Uno Platform Studio, as well as to launch a 7-day .NET Holiday Challenge with $10,000 in prizes.
