Xamarin To .NET MAUI Migration
NextPage helps teams audit, stabilize, and migrate Xamarin.Forms, Xamarin.Android, and Xamarin.iOS apps to .NET MAUI with dependency cleanup, UI migration planning, API checks, regression testing, app-store readiness, and phased rollout support.
Built for
Teams with a working Xamarin app that still supports customers, field teams, patients, partners, or internal operations but now carries dependency, developer-availability, app-store, security, and roadmap risk.
A practical migration roadmap that separates audit findings, dependency risk, UI migration work, API updates, QA coverage, and rollout waves.
A maintainable .NET MAUI app foundation that preserves critical Xamarin workflows while reducing unsupported framework and dependency risk.
A release plan with feature-parity checks, device evidence, app-store readiness, crash monitoring, and post-migration support priorities.
Why this matters
The best outsourcing and software projects work because expectations, ownership, and delivery rituals are clear from the first week.
The Xamarin app still works, but support, hiring, dependency updates, SDK compatibility, and app-store release confidence are getting weaker.
Custom renderers, platform-specific code, native libraries, plugins, and old NuGet packages make the migration harder than a simple framework upgrade.
Business stakeholders need feature parity, risk visibility, and release sequencing before approving a rewrite or modernization budget.
Backend APIs, authentication, push notifications, offline sync, payments, analytics, and admin workflows must keep working during the migration.
The team needs a QA matrix that covers existing customer journeys across devices, OS versions, permissions, network states, and app-store submission requirements.
A big-bang replacement can interrupt users, so the migration needs phased rollout, rollback thinking, and support ownership.
What we build
We shape the scope around the result you need, the systems you already have, and the first release that can create value.
We inspect the existing Xamarin app before recommending a path so hidden dependencies, custom renderers, plugin risk, and release constraints are visible early.
We decide how the migrated app should be structured around shared C# logic, platform-specific behavior, dependency injection, navigation, state, storage, and backend contracts.
Older Xamarin UI patterns need careful treatment. We map custom renderers, effects, controls, layouts, resources, and platform-specific views to maintainable .NET MAUI equivalents.
We replace or update packages, SDKs, analytics, crash reporting, payments, maps, camera, BLE, push, and third-party integrations that can block modern builds.
The migration is not done until the app passes real release evidence across devices, OS versions, critical journeys, offline states, and store requirements.
We plan migration waves around business risk: stabilize first, migrate critical flows, test parity, release safely, then address post-launch modernization and roadmap work.
Technology stack
A successful migration needs more than framework syntax changes. We plan the app around C# architecture, native platform constraints, backend services, QA evidence, and release operations.

Delivery model
We keep discovery practical, ship in visible increments, and make ownership clear so you can scale with confidence.
We review code structure, dependencies, custom renderers, native code, APIs, auth, analytics, crash reporting, app-store history, and critical user journeys.
You get a phased plan that explains what can move directly, what needs replacement, what should be stabilized first, and how .NET MAUI compares with other modernization options.
We move shared logic, UI, platform-specific code, services, and integrations in visible increments while validating critical workflows against regression evidence.
We support beta tracks, app-store submissions, crash monitoring, user feedback, urgent fixes, and the next modernization backlog after the migration is live.
Engagement options
Choose the model that fits your current stage. We can start small, add specialists, or run a full product pod.
Best when you need a clear Xamarin inventory, .NET MAUI fit recommendation, risk map, QA plan, and budget range before committing to migration.
Best when the app needs a controlled Xamarin to .NET MAUI migration with feature parity, dependency replacement, QA, beta release, and store support.
Best when migration is one part of broader mobile app modernization, backend cleanup, DevOps improvement, or ongoing feature delivery.

FAQ
Clear answers help you understand how the engagement works before we get on a call.
Xamarin support ended on May 1, 2024, which increases risk around future updates, dependencies, app-store requirements, developer availability, and security maintenance. .NET MAUI gives Xamarin teams a modern C# path when the product still fits the Microsoft mobile ecosystem.
No. Some apps migrate cleanly, while others need renderer replacement, plugin swaps, API updates, native-code cleanup, UI changes, or staged rebuilding. We audit the codebase first so the migration plan reflects real risk.
A migration audit usually covers app type, package versions, native projects, custom renderers, effects, platform-specific code, API contracts, authentication, push notifications, offline behavior, analytics, crash reporting, app-store history, and critical user journeys.
Timeline depends on app size, custom UI, native integrations, package health, backend dependencies, QA depth, and release constraints. A small app may be scoped in weeks, while a business-critical app often needs phased migration and parallel QA.
Yes. We use feature-parity mapping, regression tests, staged releases, and acceptance criteria to protect important workflows. When a dependency or platform behavior changes, we make that risk explicit before implementation.
If .NET MAUI is not the safest option, we will say so. Some apps are better served by native iOS/Android, Flutter, React Native, or a mobile-first web approach depending on product behavior, team skills, and long-term roadmap.
Yes. We can support crash monitoring, bug fixes, app-store updates, dependency maintenance, analytics review, backend improvements, and roadmap work after the .NET MAUI migration is live.
