Xamarin is a framework from Microsoft for building mobile apps that run on both iPhone and Android from a single codebase written in C# on the .NET platform. It has now been folded into its successor, .NET MAUI, which carries the same idea forward. For organisations already invested in Microsoft tools, it lets one team and one language cover mobile.

For a business, the value is leverage. If your systems, skills or back office already run on .NET, sharing that language and code across mobile reduces duplication and keeps everything in one ecosystem. The honest caveat is timing , classic Xamarin has reached the end of its support, so new work should target .NET MAUI, and existing apps should plan to move.

How it works

One language across mobile

C# and .NET at the core

Apps are written in C# on the .NET platform, the same language many business systems already use. One skill set covers mobile, server and desktop.

Shared code, native runtime

The bulk of the logic is written once and shared, then compiled to run natively on iPhone and Android. Each platform still gets a real, installed app.

Native interface access

The framework exposes the full set of iOS and Android controls, so the app can use platform features rather than a stripped-down subset.

Continued as .NET MAUI

Microsoft has carried Xamarin forward into .NET MAUI, which modernises the toolkit while keeping C# and shared code at the centre.

Microsoft and Visual Studio tooling

Development uses Visual Studio, Microsoft's mature environment, with the same building, testing and debugging tools used across the .NET world.

Why we build with Xamarin

Leverage your .NET investment

We choose the .NET approach because it answers the questions a business should ask of any tool it depends on.

01
It reuses your existing skills. If your team and systems already run on C# and .NET, mobile can share that language instead of adding a separate stack.
02
It shares code across platforms. Logic written once can serve iPhone, Android and your .NET back end, which reduces duplication and the bugs that come with it.
03
It has a clear successor. Microsoft continues the approach in .NET MAUI, so the path forward is defined rather than abandoned.
04
It is backed by mature tooling. Visual Studio and the wider .NET ecosystem give solid, well-supported tools for building and maintaining the app.

What we build with Xamarin.

We work with Xamarin and its successor .NET MAUI for Cayman organisations already invested in Microsoft and .NET. That includes line-of-business apps for staff, apps that extend an existing .NET system to mobile, and internal tools where sharing logic with the server saves real effort. For these cases, keeping mobile in the same ecosystem is a sound, practical choice.

We are straight about timing. Because classic Xamarin has reached the end of its support, we build new apps on .NET MAUI and help owners of existing Xamarin apps plan a move before it becomes urgent. If your organisation has no .NET footprint, we will often suggest native or another route instead. The aim is the right fit, not a default.

Frequently asked questions

What Cayman businesses ask about Xamarin.

Is Xamarin still supported?

Classic Xamarin reached the end of Microsoft's support in 2024. Its work continues in .NET MAUI, which we use for new projects. If you have an existing Xamarin app, we can keep it running while we plan an orderly move to .NET MAUI.

What is the difference between Xamarin and .NET MAUI?

They are two stages of the same idea. .NET MAUI is Microsoft's modern continuation of Xamarin, keeping C# and shared code while improving the toolkit and adding desktop. For new work we build on .NET MAUI; the underlying approach is familiar.

Should we choose this if we do not use Microsoft tools?

Usually not as a first choice. The .NET approach shines when you already run on C# and .NET and want mobile in the same ecosystem. Without that footing, native or another cross-platform route is often a better fit, and we will say so.

Can we reuse our existing .NET code?

Often, yes. Business logic written in C# for your server or systems can frequently be shared with the mobile app, which reduces duplication and keeps rules consistent. We assess what can be shared safely before relying on it.

Do these apps run natively on both platforms?

Yes. The shared C# code is compiled to run natively on iPhone and Android, and each app installs from the store like any other. Users get a real native app, not a web page wrapped in an app shell.

We have an old Xamarin app , can you help?

Yes. We can maintain it in the short term and plan a migration to .NET MAUI so you keep your investment without staying on an unsupported framework. We will scope the move clearly so you can budget for it rather than face a surprise.

Invested in .NET already?
Let us bring it to mobile.

Tell us about your systems and we will recommend the right approach, .NET MAUI or native, and explain exactly why it suits your case.
