Xamarin Application Development Company
Xamarin Application Development Company in Canada | Cross-Platform Apps, Native Performance, and .NET MAUI Migration
Xamarin reached end of support in May 2024, but your app still ships to real users every day. Our Xamarin development services keep it healthy in the stores now and move it to .NET MAUI in stages when you are ready, never a panic rewrite. Built and maintained in Canada, in C# your own team can read.

What You Get From a Real Xamarin Team
Engineers Who Shipped Real Xamarin
Custom renderers, platform effects, and the C# and .NET stack beneath them, from apps we have run in production rather than read about. You get judgment in Xamarin app development earned on real store releases.
A .NET MAUI Plan, Not a Scare
Support ended in May 2024, so you need a route, not a rewrite quote. We keep your app store-compliant today and move it to .NET MAUI module by module, invisibly to the people using it.
Native Feel on One Codebase
Shared logic, with platform-specific UI only where it earns its keep. The app feels native on iOS and Android, clears review, and skips the lag of a generic wrapper.
Code Your Developers Can Keep
Clean MVVM, tests on the logic that matters, and modules documented for the next person to open. When we step back, your team extends the app without a ticket to us.

Where Xamarin Builds Break, and How We Keep Yours Shipping
Business Priorities
Industry Gaps
Our Proven Advantage
Built to Pass Enterprise Security Review
Our Xamarin development carries ISO 27001, ISO 9001, and ISO 20000 certification. Where the app handles regulated data we layer in HIPAA and GDPR controls, with SOC 2 reporting on request, and on-device storage, identity, and update integrity are handled by design.
Book a Free Xamarin Development Consultation
Grab a time and walk us through your app, the SDK version it runs on, and how pressing the .NET MAUI move is for you. We will sketch a Xamarin development plan that keeps it in the stores, and you walk away with a clear sense of timeline and cost. You are under no obligation to proceed.
Among Canada's Most-Reviewed Xamarin Development Companies
Teams judge a Xamarin development company on what happens after go-live, and that is where AppStudio shows: an audit before promises, clean MVVM, and store-compliance kept current, so the app stays in the stores and keeps performing.
The Xamarin Stack We Build With
C# and .NET do the heavy lifting in our Xamarin app development, but a store-ready app leans on the tools around them too. This is what our Xamarin developers reach for on real client work, picked for native performance, testability, and code that survives a maintenance handover.

How a Xamarin App Goes From Audit to Store
The shape of a Xamarin app is set in the first sprint: where code is shared versus native, how the MVVM layers sit, and how it talks to your backend. At AppStudio we settle those before feature work, through disciplined cross-platform development, which is why our builds stay maintainable as screens pile up.
The work moves in clear phases, so the Xamarin development stays predictable: budget, timeline, and any migration path are agreed up front, and you watch it run on real devices throughout, not only at the end.
The result of our Xamarin development services is an app that performs like native, clears store review, carries a named path to .NET MAUI, and stays something your team is glad to open, not the file nobody wants to touch.

A Xamarin Development Company Built for the Long Haul
Xamarin earns its place when a business needs one team and one C# codebase to serve iOS, Android, and Windows, with real device access and rules that cannot be broken. That is the Xamarin application development we take on. We build and maintain cross-platform mobile apps on a codebase that is structured with clean MVVM, tested where it counts, and documented so the next developer to join can find their way around.
Bring us a greenfield app, an inherited Xamarin build, or an app stuck on an old SDK and blocked from the store. We handle cross-platform builds, enterprise line-of-business apps, backend integration, and staged migration to .NET MAUI now that Xamarin support has ended. You can also bring in a dedicated Xamarin development team to sit inside your own group, which usually moves fastest when your product knowledge already lives in house.
We work with teams across Canada, from Toronto and Ottawa through Calgary and Vancouver, and into the United States.
