Uno Platform development
Uno Platform development, from the people who build Uno
We design, build, and modernize single-codebase .NET applications for web, mobile, and desktop with Uno Platform. Our work is led by the creator of the Uno Single Project and the Uno SDK, so you get the deepest possible expertise on the framework itself.
Why this matters
The deepest Uno Platform expertise you can hire
Uno Platform lets one C# and XAML codebase run natively on iOS, Android, Windows, macOS, Linux, and the web via WebAssembly. We do not just use Uno, we help build it. Dan Siegel created the Uno Single Project and the Uno SDK that power how modern Uno apps are structured and shipped. That means fewer surprises, faster delivery, and architecture decisions grounded in how the framework actually works under the hood.
What we build
Single-codebase apps for every screen
Cross-platform apps
Native iOS, Android, Windows, macOS, and Linux apps from one C#/XAML codebase, with the performance and feel users expect.
WebAssembly web apps
Ship the same app to the browser via WebAssembly, no separate web team or rewrite required.
Pixel-perfect UIs
Design-fidelity interfaces with Uno’s Skia rendering, shared styles, and a real design-to-code workflow.
WPF, UWP & Silverlight migration
Bring legacy Windows desktop apps forward to a modern, cross-platform Uno codebase, incrementally.
Design systems
Reusable component libraries and themes that stay consistent across every target platform.
Backend & API integration
Wire your Uno app to ASP.NET Core, Azure, and third-party services with shared, testable logic.
Why AvantiPoint
Framework authors, not framework tourists
We build Uno itself
As the creator of the Uno Single Project and Uno SDK, we know the internals, the roadmap, and the right way to structure a project.
Senior by default
Every engagement is led by proven cross-platform .NET engineers, never staffed with whoever is on the bench.
Performance you can measure
We diagnose and fix the startup time, payload size, and rendering issues that trip up other Uno teams.
We stay for the long run
Pair your build with a managed service contract and we keep your Uno app healthy long after launch.

Questions
Frequently asked
What is Uno Platform?
Uno Platform is an open-source framework for building single-codebase .NET applications that run natively on iOS, Android, Windows, macOS, and Linux, and on the web via WebAssembly, using C# and XAML.
Do you really build Uno Platform itself?
Yes. Our work is led by Dan Siegel, the creator of the Uno Single Project and the Uno SDK. We contribute to the ecosystem and build production apps on it, so you get first-party expertise.
Can Uno Platform target the web?
Yes. Uno compiles your .NET app to WebAssembly so the same codebase that powers your mobile and desktop apps also runs in the browser, no separate web rewrite.
Uno Platform or .NET MAUI, which should I use?
Both are excellent single-codebase .NET options. Uno is the strongest choice when you need pixel-perfect UI fidelity and true web (WebAssembly) support from the same codebase; MAUI is a great fit for many native mobile and desktop apps. We will give you an honest recommendation for your project.
Can you migrate our WPF or UWP app to Uno?
Yes. We specialize in bringing legacy Windows desktop apps forward to a modern, cross-platform Uno codebase with a staged, low-risk plan.
How much does Uno Platform development cost?
It depends on scope and engagement model (project, dedicated team, or managed retainer). Book a call and we will put together a tailored proposal.
