/ How it runs
Six steps from the first working session to a .NET MAUI app live on every platform, with a checkpoint at the end of each.
We work with your product owners to map business goals, the target platforms and devices, and every system the app must connect to, then write the scope down before design starts.
DiscoveryIn .NET MAUI projects we decide early what lives in shared code, such as data access and validation, and what stays platform-specific. A shared architecture, usually MVVM with data binding, keeps later changes in one place.
ArchitectureScreens are designed once in XAML with shared styles, then checked on each platform, so users get a consistent user experience on phones, tablets, and desktops without losing platform conventions.
AI layout & component scaffolding DesignThe team works in short sprints with demos and code review, and XAML hot reload keeps UI feedback loops short.
AI-assisted code & test generation DeliveryUnit, UI, and integration tests run on every target platform, and quality assurance plus a security review sign off each release candidate before it reaches the app stores or the Windows desktop.
AI-generated UI and unit tests QAStore submissions, Windows packaging, monitoring, and planned .NET MAUI version upgrades keep the app on a supported version after launch.
AI-triaged monitoring & crash triage Support/ Questions, answered
You get .NET MAUI developers backed by a delivery organization of 1,000+ Brainers across 10+ global offices, with 14+ years of experience, 2,000+ brands served, and a 95% client retention rate. The eight practice areas above cover the whole app, from the shared codebase and user interface to the ASP.NET Core backend, enterprise integration, and support, so one team can own the build end to end.
.NET Multi-platform App UI (.NET MAUI) is Microsoft's cross-platform framework for creating native mobile and desktop apps with C# and XAML. From a single codebase shared across platforms, the same app can run on Android, iOS, macOS, and Windows. It is open source and is the evolution of Xamarin.Forms, extended from mobile to desktop scenarios.
Creating apps that need to reach multiple platforms from one team: customer-facing mobile apps, field and operations apps, and Windows or Mac desktop applications that share code with their mobile versions. Microsoft describes it as a framework for developers who want to share UI layout and design, code, tests, and business logic across platforms.
For .NET MAUI 10, Microsoft lists Android 5.0 (API 21) or higher, iOS 12.2 or higher, macOS 12 or higher using Mac Catalyst, and Windows 11 and Windows 10 version 1809 or higher using WinUI 3. Microsoft's docs also note that apps targeting .NET 11 require Android API level 24 or higher. Tizen support is provided by Samsung.
.NET is the platform: the runtime (Mono on Android, iOS, and macOS, and the .NET Core Common Language Runtime on Windows), the Base Class Library, and frameworks such as ASP.NET Core. .NET MAUI is one framework on top of it for the user interface of mobile and desktop apps. .NET for Android, .NET for iOS, .NET for Mac Catalyst, and WinUI 3 all share the same Base Class Library, and .NET MAUI provides a single framework for building the UIs across them.
Frontend. .NET MAUI builds the client app: the screens and the app logic that runs on the device. The backend is usually separate; on this page that is ASP.NET Core services and APIs on Azure (card /06), which the MAUI app calls. Keeping both in C# lets the team reuse models and validation code on the client and the server.
In effect, .NET MAUI consolidates the Android, iOS, macOS, and Windows APIs into a single API, which Microsoft describes as a write-once run-anywhere developer experience, while still giving deep access to each native platform. Your code talks mainly to the .NET MAUI controls and API layer, which calls the native platform APIs, and app code can also call platform APIs directly when required.
It compiles into native app packages. Per Microsoft, iOS apps are fully ahead-of-time (AOT) compiled from C# into native ARM assembly code, Android apps compile into intermediate language that is just-in-time (JIT) compiled to a native assembly when the app launches, and Windows apps use WinUI 3 to create native apps. Speed in .NET MAUI applications still depends on how they are built, so we profile on real devices and improve performance where a screen is slow.
It suits enterprise applications that already run on Microsoft technology: teams reuse their C# skills, share code with ASP.NET Core services, and connect the app to Azure, ERP, CRM, and identity systems (cards /06 and /07). .NET MAUI is governed by the Microsoft Modern Lifecycle and aligns with the .NET release cadence, so plan upgrades in step with .NET releases.
Microsoft says a major version of .NET MAUI receives support for a minimum of 6 months after its successor ships. .NET MAUI 10 was released on November 11, 2025, with end of support listed as May 11, 2027, and .NET MAUI 9 reached end of support on May 12, 2026. To receive technical support from Microsoft, you need to be on the latest servicing update.
Yes. Xamarin support ended on May 1, 2024, for all Xamarin SDKs, including Xamarin.Forms, and Microsoft says existing Xamarin.Forms projects should be migrated to .NET MAUI. Card /03 and the Xamarin to .NET MAUI accelerator above cover that path: an audit of the project, conversion, handler migration, and parity testing on every target platform.
Yes. .NET MAUI provides cross-platform APIs for device features such as GPS, the accelerometer, compass, and gyroscope, network connectivity, secure key/value storage, and text-to-speech. Card /04 covers sensors, Bluetooth, and camera, and when a feature has no cross-platform API, our developers call the native APIs directly.
Yes. Windows apps built with .NET MAUI use the WinUI 3 library to create native apps that target the Windows desktop, and macOS apps use Mac Catalyst. The Native to .NET MAUI accelerator above consolidates separate desktop and mobile codebases onto one MAUI codebase. Building apps for iOS and macOS requires a Mac.
Blazor Hybrid runs Blazor web UI inside a native .NET MAUI shell, so web UI and .NET logic can be shared between a web app and native apps (card /05). For .NET MAUI 10, Blazor apps need Android 7.0 (API 24) or higher and iOS 16.4 or higher, plus an updated platform-specific WebView control.
Visual Studio on Windows, where .NET MAUI apps for Android, iOS, and Windows can be built, though a networked Mac is required for iOS development. Visual Studio Code with the .NET MAUI extension also works on Windows and macOS. Day to day, the team relies on XAML hot reload and .NET hot reload, NuGet packages, and CI pipelines that build every platform.
Both let one team build cross-platform applications from a shared codebase. Flutter uses Dart and React Native uses JavaScript, while .NET MAUI uses C# and XAML, which suits teams already on .NET, Azure, and Microsoft identity systems. The better choice is usually the one that matches your team's language and the systems the app must connect to.
It is a strong fit when your team works in C# and .NET, when the app must reach both mobile and desktop, or when a Xamarin.Forms app needs a supported successor. It is open source, Microsoft ships servicing updates on the same monthly cycle as the rest of .NET in months where there are fixes, and each major version ships with a .NET release. If your team and backend are not on .NET, compare it with other frameworks first.
One codebase in C# and XAML for Android, iOS, macOS, and Windows; a single project that uses multi-targeting instead of one project per platform, which Microsoft says gives a simplified and consistent cross-platform development experience; hot reload for XAML and C#; and cross-platform APIs for device features. For a business, that usually means one team, one release train, and less duplicated work across different platforms: a fix in the shared code reaches every platform in the same release, and existing .NET libraries and NuGet packages can usually be reused.
One of the key aims of .NET MAUI, in Microsoft's words, is to implement as much of your app logic and UI layout as possible in a single code-base, adding platform-specific source code and resources only where needed. Code sharing is highest in the shared logic layer: business rules, data access, and validation. The share of UI depends on how much platform-specific design the app needs; the Native to .NET MAUI accelerator above cites 60% of screens shared across desktop and mobile.
Unit testing covers the shared business logic and data transformations and guards against regressions, UI testing runs on device simulators and real phones, tablets, and PCs, integration tests check every API the app calls, and manual exploratory testing catches platform quirks. The AI-generated UI and unit tests described above run on every target device, and quality assurance signs off each platform before release.
Security starts in the shared code: tokens and secrets go into the secure key/value storage .NET MAUI exposes, sign-in uses browser-based authentication flows with your identity provider, APIs are called over authenticated connections, and dependencies are kept patched. Microsoft notes that .NET MAUI updates may include a mix of security and non-security fixes in a single update, so staying on the latest servicing update matters.
Yes. The On-Device AI Accelerator above ships on-device intelligence inside the MAUI client with ML.NET and platform ML runtimes, covering vision, OCR, and personalization, and predictions can run even offline. AI also sits in the build itself, with copilots for code, tests, and migration.
It depends on the number of platforms, the screens and integrations, whether you are migrating from Xamarin.Forms or starting fresh, and how long you need support afterward. There is no rate card on this page; after a working session, we estimate the project against a written scope.
Yes. Working hours that overlap with your time zone are agreed on at the start of the engagement, along with the channels, sprint rhythm, and demos the team will use.
Managed .NET MAUI support, as card /08 describes: SDK and .NET MAUI version upgrades, NuGet package updates, monitoring, AI-triaged crash triage, and continuous optimization based on API performance and user feedback, 24×7. Upgrades are planned against Microsoft's published support dates so the app stays on a supported version.
The eight industries above: retail and eCommerce, healthcare, finance and fintech, automotive, real estate, logistics, media, and education.
Look for hands-on C# and XAML experience, a clear plan for code sharing and platform-specific work, a migration path if you have Xamarin.Forms code, and a testing approach that covers unit, UI, and integration tests. Ask for a technical walkthrough of how they would structure your app, and how they plan .NET MAUI version upgrades within Microsoft's support window.
