Xamarin & .NET MAUI Development
for Perth, Melbourne, Sydney, Brisbane businesses.
Cross-platform mobile apps built in C# for .NET teams. Enterprise mobile, field apps, and internal tools that share code with your ASP.NET Core backend.
Xamarin to .NET MAUI migration. Xamarin to React Native or Flutter when that is the better path. Perth-based, Australia-wide.
C# mobile development for .NET-centric organisations
Xamarin and its successor .NET MAUI let C# developers build Android and iOS apps without learning a different language. If your backend is ASP.NET Core and your team knows C#, the mobile layer can speak the same language. That is the core pitch, and for the right project it delivers genuine value.
We build new .NET MAUI apps, migrate existing Xamarin apps to .NET MAUI, and — when .NET MAUI is not the right path — migrate Xamarin apps to React Native or Flutter. We are honest about when each option makes sense.
Xamarin support ended in May 2024. If you are still running a Xamarin app, the clock is ticking on OS compatibility and security patches. Migration is not optional — the question is where to migrate to.
Xamarin & .NET MAUI development — by project type
Enterprise mobile apps, field tools, internal workflow apps, Xamarin migration, and cross-platform builds for .NET teams.
Enterprise Mobile Apps with .NET Backend
Cross-platform mobile apps sharing code with your .NET backend. C# on the server, C# on the mobile devices. For organisations that have invested in Microsoft infrastructure, Xamarin and .NET MAUI let the same development team build both the backend and the mobile layer.
Line-of-business apps that connect to existing .NET APIs, SQL Server databases, Azure services, and Active Directory. The mobile app is an extension of your enterprise system, not a separate technology stack requiring different skills.
This is the main reason organisations chose Xamarin — and the main reason .NET MAUI exists. If your backend is .NET and your team knows C#, building mobile in the same language reduces cost and simplifies everything from hiring to debugging.
Field Service & Data Collection Apps
Mobile apps for field workers — inspections, audits, service reports, and delivery verification. Data capture with validation, photo attachments, GPS location, and offline storage with background sync.
Xamarin/.NET MAUI handles offline scenarios well with SQLite and local storage. Field apps need to work without connectivity. Data is captured locally and syncs to the .NET backend when the device reconnects.
Common in mining, utilities, construction, and logistics where Android devices are deployed to workers in areas with unreliable connectivity. The same codebase runs on Android phones, tablets, and ruggedised devices.
Internal Operations & Workflow Apps
Apps for internal teams — job allocation, time tracking, approval workflows, inventory management, and internal communications. Deployed via MDM to company devices or distributed through enterprise app stores.
Integration with Microsoft 365, SharePoint, Teams, and Azure AD for single sign-on. These apps slot into the existing Microsoft ecosystem that many Australian enterprises already run.
The app does not need to win design awards. It needs to work reliably, integrate with existing systems, and make staff more productive. Xamarin/.NET MAUI delivers functional, solid internal tooling.
Xamarin to .NET MAUI Migration
Xamarin support ended in May 2024. If you have a Xamarin.Forms or Xamarin.Native application, it needs to be migrated to .NET MAUI to continue receiving updates, security patches, and compatibility with current mobile OS versions.
Migration from Xamarin.Forms to .NET MAUI is incremental — not a ground-up rewrite. The XAML is similar, the C# logic mostly transfers, and the project structure changes are well-documented. Microsoft provides migration tooling.
The tricky parts are custom renderers (replaced by handlers in MAUI), third-party NuGet packages that may not have MAUI versions, and platform-specific code that needs updating. We handle these edge cases and test thoroughly on real devices.
Cross-Platform Apps for .NET Teams
For teams that know C# and .NET, .NET MAUI provides a genuine cross-platform mobile option without learning JavaScript, Dart, or Swift. One language, one IDE (Visual Studio), one team for backend and mobile.
Android and iOS from the same C# codebase. Shared business logic, validation, data models, and API clients. Platform-specific UI where needed. The economics are straightforward — one team, one language, two platforms.
Caveat: the .NET MAUI ecosystem is smaller than React Native or Flutter. Third-party component libraries, community packages, and hiring market are more limited. For projects where .NET alignment is the priority, that trade-off is worth it. When it is not, we recommend React Native or Flutter instead.
When C# makes sense for mobile development
C# from backend to mobile — one language, one team
The core value proposition of Xamarin/.NET MAUI is language unification. Your backend API is C#. Your mobile apps are C#. The same developers work on both. No JavaScript, no Dart, no language context switching.
Shared business logic between backend and mobile. Validation rules, data models, calculations, and service interfaces written once and used everywhere. When the business logic changes, you change it in one place.
For organisations with existing .NET investment — developers, infrastructure, intellectual property — this alignment matters. A new mobile project does not mean hiring a React Native or Flutter team. Your existing team can do it.
Deep integration with the Microsoft ecosystem
Azure AD for enterprise authentication. Azure DevOps for CI/CD. Visual Studio for development. NuGet for package management. Application Insights for monitoring. The mobile development workflow connects to the same Microsoft tools your backend uses.
For organisations running Microsoft 365, Azure, and SQL Server, .NET MAUI mobile apps integrate naturally. Single sign-on with corporate accounts. SharePoint and Teams integration. Azure Blob Storage for file handling.
Microsoft maintains .NET MAUI as part of the broader .NET ecosystem. Releases are aligned with .NET versions. Support and updates come from the same team that maintains ASP.NET Core and Entity Framework.
Full native API access when you need it
.NET MAUI provides access to every native platform API through C# bindings. Camera, GPS, Bluetooth, NFC, biometrics, file system, and device sensors are all available. When the cross-platform abstraction is insufficient, you can write platform-specific code in the same project.
Handlers (replacing Xamarin's custom renderers) let you customise native controls without leaving C#. Need a platform-specific behaviour on iOS but not Android? Conditional compilation handles it cleanly.
This is the same advantage Xamarin always had — native performance and native API access, with a shared C# codebase. .NET MAUI modernised the architecture, but the core promise is unchanged.
When Xamarin/.NET MAUI is — and isn't — the right choice
.NET MAUI is the right choice when your organisation is invested in .NET and C#, your backend is ASP.NET Core, and you want one team building everything. The language alignment provides genuine cost and complexity savings.
It is not the right choice when the hiring market matters (React Native and Flutter developers are far more available), when third-party UI component richness matters, or when the app is consumer-facing and needs the latest design trends.
We are honest about this. If React Native or Flutter would serve your project better, we say so. Xamarin/.NET MAUI has real strengths in enterprise contexts, but it is not the default recommendation for every mobile project.
Have a Xamarin app that needs attention?
Xamarin to .NET MAUI migration, Xamarin to React Native/Flutter, maintenance, performance fixes, or app takeover.
Xamarin to .NET MAUI Migration
Xamarin support ended May 2024. We migrate Xamarin.Forms and Xamarin.Native apps to .NET MAUI — handlers, NuGet updates, project restructuring, and platform-specific code migration.
Xamarin to React Native/Flutter
Sometimes .NET MAUI is not the right path forward. We rebuild Xamarin apps in React Native or Flutter when the project needs a larger ecosystem, richer UI components, or a bigger talent pool.
App Takeover & Maintenance
Previous developer gone? We audit, document, and take over your Xamarin or .NET MAUI app. Bug fixes, dependency updates, and ongoing feature development.
Performance Optimisation
Slow startup, UI lag, memory leaks, or excessive battery usage. We profile and fix performance issues in Xamarin and .NET MAUI apps on real Android and iOS devices.
Dependency & NuGet Updates
Outdated NuGet packages, breaking changes, and compatibility issues with new OS versions. We update dependencies and test to keep the app current and functional.
.NET MAUI Version Upgrades
Upgrading between .NET MAUI versions (e.g., .NET 7 to .NET 9). We handle breaking changes, new API adoption, and testing across Android and iOS.
Xamarin End of Life
Xamarin support ended May 2024. Time to migrate.
No more security patches, no more OS compatibility updates. We migrate to .NET MAUI, React Native, or Flutter — whichever best fits your project and team.
Common Xamarin & .NET MAUI scenarios
If one of these sounds like your project, we have done it before.
.NET Enterprise Mobile App
Extending your ASP.NET Core backend to mobile. Same C# language, shared business logic, Azure AD sign-on, and Visual Studio for the entire stack.
Xamarin to MAUI Migration
Existing Xamarin app that needs migrating to .NET MAUI before it falls behind on OS compatibility and security updates. Incremental, not a rewrite.
Field Data Capture App
Offline-capable data collection for field workers. Inspections, audits, service reports. Syncs to your .NET backend when connectivity is available.
Internal Workflow Tool
Approval workflows, job allocation, time tracking, and operations management deployed to company devices. Microsoft 365 and Azure AD integration.
Xamarin to React Native Rebuild
When .NET MAUI is not the right path — larger ecosystem, richer UI components, bigger hiring pool. We rebuild your Xamarin app in React Native or Flutter.
Cross-Platform Business App
Android and iOS from one C# codebase. Customer portals, booking systems, or operational tools for .NET-centric organisations.
Common Xamarin migration and upgrade paths
From Xamarin to .NET MAUI, Xamarin to React Native/Flutter, and .NET MAUI version upgrades.
Common Xamarin/.NET MAUI stack combinations
Xamarin/.NET MAUI is the mobile layer. These are the backends, platforms, and alternatives we pair it with.
Xamarin/.NET MAUI + ASP.NET Core
The default stack. C# backend and C# mobile. Shared models, validation logic, and API contracts. Azure DevOps CI/CD for the entire pipeline.
Xamarin/.NET MAUI + Azure
Azure App Service backend, Azure AD authentication, Azure DevOps CI/CD, Application Insights monitoring, and Azure Blob Storage for file handling.
Xamarin/.NET MAUI + SQL Server
SQL Server backend with Entity Framework Core. The standard .NET data stack. Azure SQL for cloud, or on-premises SQL Server for existing infrastructure.
.NET MAUI + Blazor Hybrid
Blazor components rendered natively on mobile. Share web UI components between your Blazor web app and .NET MAUI mobile app. C# and Razor from browser to device.
React Native Alternative
When .NET alignment is not required, React Native provides a larger ecosystem, more third-party components, and a bigger hiring market. JavaScript shared with web projects.
Flutter Alternative
When UI fidelity and rendering performance are priorities, Flutter provides a custom rendering engine with excellent animations. Dart language, Material and Cupertino widgets.
We had a Xamarin.Forms app connected to our .NET backend that was falling behind on OS updates. HELLO PEOPLE migrated it to .NET MAUI in eight weeks. The shared C# codebase with our API is exactly why we chose this path — our team maintains everything in one language.
Common questions about Xamarin and .NET MAUI development
Is Xamarin still supported?
No. Xamarin support ended in May 2024. Microsoft replaced it with .NET MAUI (Multi-platform App UI), which is the supported successor. Existing Xamarin apps will continue to work but will not receive security patches or OS compatibility updates. Migration to .NET MAUI is recommended.
What is .NET MAUI?
.NET MAUI is Microsoft's cross-platform framework for building Android, iOS, macOS, and Windows applications using C# and XAML. It replaces Xamarin.Forms and is part of the .NET ecosystem. Same concept — C# cross-platform mobile — with modernised architecture, improved performance, and alignment with current .NET releases.
Should I migrate to .NET MAUI or switch to React Native/Flutter?
It depends on your situation. If your organisation is invested in .NET and C#, your backend is ASP.NET Core, and your team knows C# — .NET MAUI is the natural path. If you need a larger component ecosystem, a bigger hiring market, or shared code with web projects — React Native or Flutter is likely better. We advise honestly based on your specific context.
How much does Xamarin/.NET MAUI development cost?
A .NET MAUI cross-platform business app typically starts from $25,000 to $60,000 depending on complexity. Xamarin to .NET MAUI migration projects range from $10,000 to $40,000 depending on the app's size and complexity. We provide fixed-price quotes after scoping.
Can I share code between my .NET backend and .NET MAUI app?
Yes. Shared class libraries for models, validation, business logic, and API contracts are one of the main advantages. The same C# code runs on the server and on the mobile device. This reduces duplication and keeps business rules consistent.
Can you take over our existing Xamarin app?
Yes. We take over Xamarin and .NET MAUI projects. We audit the codebase, assess the migration path, and either maintain the app as-is, migrate to .NET MAUI, or recommend a rebuild in React Native/Flutter if that better serves the project.
Does .NET MAUI support offline functionality?
Yes. .NET MAUI supports SQLite and local storage for offline data capture. Combined with background sync and a REST API backend, the app works without connectivity and syncs when the device reconnects.
How long does a Xamarin to .NET MAUI migration take?
A small Xamarin.Forms app can be migrated in 4–8 weeks. Larger apps with custom renderers, complex platform-specific code, and many third-party NuGet packages take 8–16 weeks. We assess each project individually and provide a migration plan with timeline.
