How to Hire Xamarin Developers: The Master Guide

The store deadlines your Xamarin app already missed, when .NET MAUI is the right move and when a rewrite is, and what to test in an engineer who will carry the migration.

Read the guide now
Xamarin use cases

What companies build when they hire Xamarin developers.

Six problems U.S. teams bring to us when they still run a Xamarin app, from an update the stores will no longer accept to the question of whether to migrate at all.

  • Get a Xamarin app shipping to the stores again

    Microsoft's last Xamarin SDKs target Android API 34 and Xcode 15. Google Play now requires API 36 for app updates and the App Store requires the iOS 26 SDK, so the first job is moving the app to .NET for Android and .NET for iOS and getting a release through review.

    • .NET 10
    • .NET for Android
    • .NET for iOS
    • SDK-style projects

  • Xamarin.Forms to .NET MAUI, without a rewrite

    Namespaces, project structure, Xamarin.Essentials APIs and DependencyService calls moved to their .NET MAUI equivalents, with the screens checked on real devices because default layout values changed and a page can compile and still look wrong.

    • .NET MAUI 10
    • .NET Upgrade Assistant
    • CommunityToolkit.Mvvm
    • Shell

  • Custom renderers moved to handlers

    Some Xamarin.Forms renderers can be reused in .NET MAUI through compatibility shims; the rest have to become handlers. Engineers who have done it know which ones to port first and which platform code to keep.

    • MAUI handlers
    • Property mappers
    • Platform code
    • Effects

  • Replace packages and bindings that stopped at Xamarin

    An audit of every NuGet dependency, a .NET MAUI-compatible version or replacement for each one, and native bindings for Android and iOS SDKs rebuilt for modern .NET, so a single abandoned package does not block the whole migration.

    • NuGet
    • Android binding libraries
    • iOS binding projects
    • Native Library Interop

  • Rebuild the mobile pipeline after App Center

    App Center Build, Test and Distribution retired on March 31, 2025, and Analytics and Diagnostics end on March 31, 2027. Signing, builds, TestFlight and Google Play releases, plus crash reporting, move to a pipeline your team owns.

    • Azure Pipelines
    • GitHub Actions
    • TestFlight
    • Google Play Console

  • Decide: .NET MAUI, native or React Native

    A migration plan that starts with the app you have: how much C# business logic it carries, how custom the UI is, and who will maintain it. Sometimes the answer is .NET MAUI, sometimes a rewrite in Swift and Kotlin or React Native.

    • .NET MAUI
    • React Native
    • Swift
    • Kotlin
Smart hiring, better ROI

The real cost to hire Xamarin developers:
Latin America vs. the U.S.

The U.S. figure is base salary only, before payroll taxes, benefits, equipment and recruiting fees. Ours is all-inclusive, priced on our .NET rate, with the same working hours for standups, code review and store releases.

U.S. software developer$135,980Median base salary (BLS, May 2025). Employer taxes, benefits and hiring costs come on top.
LatAm senior via BEON.tech33% to 45% below U.S. median base
$74.4K – $91.2KAll-inclusive, same vetting bar, same time zone
Cost breakdownU.S. software developerLatAm senior (BEON.tech)
Base salary$135,980 median (BLS, May 2025)$6,200 – $7,600 / month, all-inclusive
Payroll taxes & employer contributionsPaid by employer, on top of salaryIncluded
Benefits & insurancePaid by employer, on top of salaryIncluded
Equipment & onboardingPaid by employerIncluded
Recruiting / sourcing feesInternal recruiting time or agency feeIncluded, no separate fee
Total annual cost$135,980 + employer costs$74,400 – $91,200

If you decide to rewrite instead of migrating, those engineers are priced on their own stack: React Native from $6,000 to $7,500 per month, native iOS from $6,300 to $7,900, and native Android from $6,500 to $8,000. Where an engineer lands inside the range depends on seniority and scope: keeping a Xamarin.Forms app patched and leading its migration to .NET MAUI with custom bindings do not price the same. We quote after a 30-minute call.

Xamarin vetting process

How BEON.tech evaluates the top 1% of Latin American Xamarin developers.

Four gates, all of them before you spend a minute interviewing. The counts are per 100 engineers who enter the process; 20,775 have so far. Every rate below says which stage it measures.

1
Inbound + outbound
SourcingHalf inbound, half outbound: LinkedIn and referrals, senior .NET engineers with shipped Xamarin or .NET MAUI apps in their work history, and mobile engineers who have moved Xamarin apps to other stacks. The count is who answered and entered the process, not who we contacted.
Not counted as rejectionsProfiles where Xamarin is a course certificate or a line in a skills list with no app behind it, and engineers not open to a move, never entered. We don't count them as filtered.
2
In English · Live
Cultural fit & English collaborationIn English: a live stand-up, a pull request explanation to a reviewer who disagrees, and a trade-off explained to a non-engineer, such as why the app cannot ship an update until the first migration step lands. We want a blocker surfaced on day two, not week three. The hardest gate: only 30% clear it.
Cut at this stageEngineers whose English is fine on paper and breaks in real-time work, and anyone who waits to be told what to do.
3
Senior-led · Stack-specific
Technical interviewOne senior-led session in the stack the engineer would use on your team: .NET for Xamarin and .NET MAUI work, or React Native, iOS or Android if you are rewriting. In .NET, the coding exercise extends an existing C# solution, following its architecture instead of rewriting it. Technical Q&A covers C# fundamentals such as async/await, dependency injection lifetimes and data access. AI judgment: reviewing generated code that compiles but hides a problem. 47% pass.
Cut at this stageSenior-titled engineers with years of production work who cannot explain the C# fundamentals underneath it. Migration code is where that gap shows: an app that moves from Xamarin.Forms to .NET MAUI also moves to a new dependency injection model and a new app lifecycle.

    The BEON.tech advantage

    Why U.S. companies choose BEON.tech to hire Xamarin developers.

    Since 2017, BEON.tech has connected leading U.S. companies with the best tech talent in Latin America. We match each hiring need with the right people: one senior engineer to get a Xamarin app releasable again, or a squad that takes it to .NET MAUI while the current version keeps working.

    • High-end vetting process

      Xamarin shows up on many .NET résumés because of one project years ago, so we act as your filter. Only 30% of the engineers who enter our process clear cultural fit and English, and 47% of those who reach the technical interview pass it. You meet the ones who wrote working C# live and can explain what changes when Xamarin code moves to .NET MAUI.

    • Strong industry experience

      #1 for IT staffing worldwide in Clutch organic rankings since 2022, and the top-ranked B2B company in Argentina. When companies find talent that stays, they don't go anywhere else.

    • Time-zone alignment

      Every BEON.tech developer works in a LatAm time zone with 0 to 4 hours of overlap with U.S. teams. App review rejections, a failed signing step or a crash spike after a release get handled during your working day, not overnight.

    • Long-term retention

      88% of the engineers we place are still on the team after year one, with an average tenure of 2.9 years. A migration from Xamarin to .NET MAUI takes months, and .NET MAUI itself moves to a new major version every year. The engineer who carried the first move is the one you want for the next one.

    • Speed without compromising quality

      First Xamarin profiles in 24–48 hours and a 2-week start, without lowering the bar. That matters when your next store update is already blocked.

    Xamarin retention framework

    The stability engine: our Talent Experience Management™ Framework.

    Engineers who have taken a production Xamarin app to .NET MAUI are a small group, and every company facing the same store deadlines is looking for one. Our framework is how 88% of the engineers we place stay past year one.

    1. From day one

      A dedicated Coach, exclusively yours

      Your Talent Experience Manager™ knows the actual work your engineer does, so retention conversations are about that work, not a generic satisfaction survey.

      In practice
      • They know whether your engineer is patching a Xamarin app for current users, porting renderers to handlers, or rebuilding the release pipeline.
    2. Ongoing

      Career advancement and recognition means retention

      Experienced engineers stay when they see a future. We map the paths Xamarin work actually offers and tie each one to work on your roadmap.

      The paths we map
      • Xamarin maintenance into .NET MAUI and modern .NET
      • Mobile .NET into full stack with ASP.NET Core
      • Cross-platform into native iOS or Android
      • Senior engineer into mobile tech lead
    3. Biweekly

      Proactive monitoring, no resignation surprises

      Biweekly check-ins track the signals that come before a resignation. All of it surfaces before a notice period does.

      Signals we track
      • A senior kept patching a Xamarin app with no migration date on the roadmap.
      • Being the only person with the signing certificates and the Mac build machine.
      • An inbound offer for a .NET MAUI role at a higher band.
    4. Every 6 months

      The 6-month recalibration

      Every six months we run a formal review on performance, compensation and scope, where a pay gap gets addressed on your terms instead of in a counteroffer.

      Why it matters in Xamarin
      • The market pays differently for engineers who maintain Xamarin code and engineers who have shipped a .NET MAUI migration to the stores. An engineer who leads yours moves from the first group to the second on your project, and the review is where that gets recognized.

    Support

    Any questions?
    We got you.

    Here you'll find answers to the most common questions about hiring Xamarin developers with BEON.tech. If you need more details, feel free to reach out!

    • Is Xamarin dead? When did Xamarin support end?

      Microsoft ended support for all Xamarin SDKs, including Xamarin.Forms, on May 1, 2024 (Microsoft Xamarin support policy). There are no more fixes or security updates, and the last Xamarin SDKs target Android API 34 and Xcode 15. Microsoft's path forward is .NET MAUI for Xamarin.Forms apps and .NET for Android and .NET for iOS for native Xamarin apps.

    • Can we still publish updates to our Xamarin app?

      Not without moving it to .NET first. Since April 28, 2026, App Store uploads must be built with the iOS 26 SDK (Apple), and since August 31, 2026, Google Play requires app updates to target Android 16, API level 36 (Google Play). Installed copies keep working, but on Google Play an app below the target level stops being available to new users on newer Android versions.

    • How much does it cost to hire a Xamarin developer?

      A senior LatAm Xamarin developer through BEON.tech is priced on our .NET rate: $6,200 to $7,600 per month all-inclusive ($74,400 to $91,200 per year). For reference, the U.S. median base salary for software developers is $135,980 (BLS, May 2025), before employer costs.

    • How long does it take to hire a Xamarin developer?

      With BEON.tech you receive a vetted shortlist in 24–48 hours, and most engineers start within two weeks of the first call, including your own interview rounds.

    • Do I need a Xamarin developer or a .NET MAUI developer?

      Usually one person who is both. The engineer has to read and debug the Xamarin code you run today and write the .NET MAUI code you will run tomorrow. Someone who only knows .NET MAUI will struggle with your renderers and old packages; someone who only knows Xamarin will write Xamarin patterns in .NET MAUI.

    • How hard is a Xamarin to .NET MAUI migration?

      Microsoft states that projects don't need to be rewritten, but every project must become SDK-style, and after running the .NET Upgrade Assistant most apps still need more work (Microsoft Learn). The effort depends on how many custom renderers, native bindings and platform-specific code paths you have, and on which NuGet packages have no .NET MAUI version. We scope it with you on the first call.

    • Should we migrate to .NET MAUI or rewrite in React Native, Flutter or native?

      If the app carries a lot of C# business logic and your backend team is in .NET, .NET MAUI keeps both. If the UI is highly custom, performance-sensitive or leans on new platform APIs, native is often the better call; see how we vet native iOS engineers. If your web team already works in React, a rewrite in React Native lets you share people and code.

    • What happens to our Xamarin.Forms custom renderers?

      .NET MAUI replaces renderers with handlers. Renderers that derive from a short list of base classes, such as VisualElementRenderer, FrameRenderer or ListViewRenderer, can be reused through compatibility shims; the others have to be ported. Most teams reuse where they can to ship sooner, then move the rest to handlers.

    • What should I test in a Xamarin or .NET MAUI developer interview?

      Test migration judgment on your kind of code. Ask the candidate how they would move a Xamarin.Forms custom renderer to a handler, what they check when a NuGet package has no .NET MAUI version, and how they would replace DependencyService with dependency injection. Then ask how they would get a release through TestFlight and Google Play from a pipeline they own.

    • How does BEON.tech vet Xamarin developers?

      Senior engineers run a live technical interview in the stack the candidate would use: .NET for Xamarin and .NET MAUI work, or React Native, iOS or Android for a rewrite. It covers a coding exercise, stack questions and a review of AI-generated code. We also assess English in conversation at C1 or above, plus team fit. Roughly 30% clear the cultural-fit and English stage, and 47% of those clear the technical interview. You receive the recording and scorecard with every profile.

    How to hire Xamarin developers: a practical guide for U.S. engineering and HR leaders.

    Written by Damian Wasserman

    Nobody starts a new app in Xamarin in 2026. Companies hire Xamarin developers because they already have one in production: a field-service app, a patient portal, a sales tool, often built between 2015 and 2020 and still used every day. Microsoft ended Xamarin support on May 1, 2024 (Microsoft Xamarin support policy), and in 2026 both app stores raised their build requirements past what the last Xamarin SDKs can produce. The job now is to keep that app working for the people who depend on it and move it to a supported stack. This guide covers how to hire for that.

    What Xamarin developers do now

    Xamarin let teams write iOS and Android apps in C#. It came in two forms: Xamarin.iOS and Xamarin.Android, which wrap each platform's native APIs, and Xamarin.Forms, a shared UI layer on top of them. Both now have successors inside .NET. Xamarin.iOS and Xamarin.Android became .NET for iOS and .NET for Android starting with .NET 6, and Xamarin.Forms evolved into .NET MAUI (.NET Multi-platform App UI).

    So a Xamarin developer in 2026 does three things. They keep the current app stable for users: crashes, backend changes, device issues. They move it to .NET for iOS and Android or to .NET MAUI so it can ship again. And they own the release process afterward, because .NET MAUI ships a new major version every year. If most of your .NET work is on the web and API side rather than the app, you are looking for .NET developers instead.

    The deadlines your app faces

    DateWhat happenedWhat it means for a Xamarin app
    May 1, 2024Xamarin support ended (Microsoft)No fixes or security updates. Last SDKs target Android API 34 and Xcode 15.
    March 31, 2025App Center Build, Test, Distribution and CodePush retired (Microsoft Learn)Many Xamarin teams built and distributed through it. The pipeline has to be rebuilt.
    April 28, 2026App Store uploads must use the iOS 26 SDK (Apple)A Xamarin.iOS build cannot meet it.
    August 31, 2026Google Play updates must target API 36 (Google Play)A Xamarin.Android build cannot meet it. Extensions run to November 1, 2026.
    March 31, 2027App Center Analytics and Diagnostics endCrash reporting has to move before then.
    May 11, 2027.NET MAUI 10 support ends (Microsoft)Even after migrating, plan an upgrade every year.

    The last row is the one teams miss. A .NET MAUI major version is supported for at least six months after its successor ships, which in practice means about 18 months. .NET MAUI 9 already reached end of support on May 12, 2026. Migrating off Xamarin is a one-time project; staying current on .NET MAUI is a yearly one.

    .NET MAUI, native or rewrite

    PathKeepsBest whenWatch out for
    Xamarin.Forms to .NET MAUIC# UI and business logic, most XAMLForms-heavy business apps, a .NET backend team, limited budget for a rewriteRenderers, packages without a .NET MAUI version, layout differences
    Xamarin.iOS/Android to .NET for iOS/AndroidNative UI code and C# logicApps already written against native APIs in C#Bindings and build tooling still need work
    Rewrite in React NativeYour API; UI and logic are rebuiltA React web team that will own the appA full rewrite, usually run in phases
    Rewrite in Swift and KotlinYour APIHighly custom UI, heavy device features, new platform APIs on release dayTwo codebases and two teams
    Rewrite in FlutterYour APIA fresh start with identical UI on both platformsA new language (Dart) for your team

    There is no universal answer. A .NET MAUI migration is usually the shortest route back to the stores for a Xamarin.Forms app, and Microsoft's own guidance is that projects don't need to be rewritten (Microsoft Learn). A rewrite makes sense when the app would need a major redesign anyway. If you go that way, see how we vet React Native engineers, native iOS engineers and Android engineers.

    The four profiles

    ProfileOwnsTypical stackHire when
    Xamarin.Forms to .NET MAUI engineerThe shared UI project, renderers, packages, the migration planXamarin.Forms, .NET MAUI, XAML, MVVM (Prism, CommunityToolkit.Mvvm)Your app is built on Xamarin.Forms

    Mobile release engineerSigning, builds, store releases, crash reportingAzure Pipelines or GitHub Actions, Mac build agents, TestFlight, Google Play ConsoleApp Center is gone and nobody owns the pipeline

    Seniority you need

    • Mid-level engineers fix bugs and build screens in an existing Xamarin or .NET MAUI app once the patterns are set.
    • Senior engineers run the migration: audit dependencies, decide which renderers to reuse and which to port, get the app building on current SDKs and through store review. This is the level most teams need first.
    • Lead engineers decide between .NET MAUI and a rewrite, sequence the work against the roadmap, and own releases and the yearly upgrade. If the mobile app is one part of a larger platform decision, that is architecture work.

    Years of Xamarin experience are a weak signal. Six years maintaining one Xamarin.Forms app is a different profile from three years that include a completed migration to .NET MAUI.

    One developer or a team

    One senior engineer can take a small or medium Xamarin.Forms app to .NET MAUI and get it releasable. Add people when there are several apps (a portfolio of internal tools is common), when native bindings to vendor SDKs are involved, or when the business will not accept a feature freeze during the migration. A common shape is two senior mobile .NET engineers, one of them owning the pipeline, plus QA on physical devices. If the backend also needs work, a full stack .NET engineer covers the API side.

    Job description essentials

    • Current stack: Xamarin.Forms or Xamarin.iOS/Android, Xamarin version, MVVM framework, how many apps.
    • Target: .NET MAUI, .NET for iOS and Android, or a rewrite, and whether that is decided.
    • The hard parts: number of custom renderers and effects, native SDK bindings (payments, scanners, maps), packages you know are abandoned.
    • Release process: how you build and sign today, who owns the Apple and Google accounts, whether App Center was part of it.
    • Backend: the API the app talks to, and whether this role touches it.
    • AI tooling: which coding assistants the team uses and how generated code is reviewed.
    • Team and hours: team size, reporting line, required overlap with U.S. hours.

    Say plainly that the role starts with a migration. Engineers who have done one look for that; engineers who want greenfield work will not last.

    Skills, layer by layer

    C# and .NET

    • async/await in UI code: keeping work off the main thread without deadlocks.
    • Dependency injection: .NET MAUI builds the app through MauiProgram and a host builder, which replaces most DependencyService usage.
    • Memory and lifecycle: event handler leaks, page lifetimes, IDisposable.

    Xamarin.Forms and .NET MAUI

    • XAML, data binding and MVVM, including moving from MessagingCenter (deprecated, and no longer public in .NET 10) to a messenger such as WeakReferenceMessenger.
    • Handlers and property mappers, and when a shimmed renderer is good enough for now.
    • Xamarin.Essentials APIs and where they live in .NET MAUI.
    • Shell navigation, CollectionView instead of ListView, and layout differences after the port.

    Platform layer

    • iOS: provisioning, entitlements, Info.plist, privacy manifests, building on a Mac with the Xcode version the .NET iOS workload expects.
    • Android: target API changes, permissions, AndroidManifest, Java and Kotlin library bindings.

    Dependencies and bindings

    • Auditing NuGet packages for .NET MAUI support and finding maintained replacements.
    • Rebuilding bindings for native SDKs, or wrapping them with a thin native layer.

    Delivery

    • CI/CD in Azure Pipelines or GitHub Actions, code signing, TestFlight and Google Play tracks.
    • Crash reporting and analytics after App Center.

    AI-assisted work

    • Using assistants for namespace and API conversions, then checking each one on a device. Generated migration code often compiles against the wrong API or hides a platform difference.

    How to interview

    1. 1Screen (30 min)Walk through a Xamarin or .NET MAUI app they shipped. What was in the shared project, what was platform code, and how releases worked.
    2. 2Live exercise (60 to 90 min) in C#Extend an existing solution without rewriting it. For a mobile role, a small Xamarin.Forms or .NET MAUI page with a view model, a service call and an error state works well.
    3. 3Migration review (30 min)Give them a Xamarin.Forms custom renderer, a DependencyService call and a packages.config with a package that has no .NET MAUI version. Ask for a migration plan.
    4. 4Team conversationHow they would explain to a product manager why the next release waits for the migration's first milestone.

    If you are rewriting instead, interview in the target stack, and ask one question about the Xamarin app: what it does that the rewrite must not lose.

    Interview questions

    • Our Xamarin.Forms app has 15 custom renderers. How do you approach them in .NET MAUI?Best answerInventory first, reuse the ones .NET MAUI can shim to ship sooner, port the rest to handlers by risk and usage, test each on both platforms.
    • A NuGet package we depend on has no .NET MAUI version. What do you do?Best answerCheck for a maintained fork or successor, look at what the app actually uses, consider replacing with a platform API or a small wrapper, and never block the whole migration on it.
    • How do you replace DependencyService in .NET MAUI?Best answerRegister services in MauiProgram and inject them, with platform implementations through partial classes or conditional registration. Knows DependencyService still exists but is not the default.
    • What is the difference between Xamarin.Android and .NET for Android?Best answerThe same platform wrapper moved into .NET: SDK-style projects, net10.0-android target frameworks, current Android APIs. Code mostly carries over; project files and tooling do not.
    • The app compiles on .NET MAUI but screens look different. Why?Best answerDefault layout values and control behavior changed between Xamarin.Forms and .NET MAUI. They test on devices and fix spacing and sizing explicitly.
    • How would you ship iOS and Android releases without App Center?Best answerA pipeline in Azure Pipelines or GitHub Actions with a Mac agent for iOS, signing handled as secrets, uploads to TestFlight and Google Play tracks, crash reporting set up separately.
    • When would you not migrate to .NET MAUI?Best answerA strong candidate names real cases: a planned redesign, a React team taking over, heavy platform-specific UI. Shows judgment, not loyalty to a framework.

    Red flags

    • Their last Xamarin work is years old and they have no view on .NET MAUI.
    • They cannot describe how their app was built, signed and released.
    • Every answer to a migration question is "rewrite it", or never is.
    • async void and .Result in exercise code outside event handlers.
    • They have never tested on a physical device.
    • They accept an AI-converted project because it compiles.

    What it costs

    The U.S. median base salary for software developers is $135,980 (BLS, May 2025), before payroll taxes, benefits, equipment and recruiting. Engineers who have led a Xamarin migration are a smaller group, and senior U.S. profiles with that experience usually sit above the median.

    A senior LatAm Xamarin developer through BEON.tech is priced on our .NET rate: $6,200 to $7,600 per month, all-inclusive ($74,400 to $91,200 per year). React Native, iOS and Android engineers for a rewrite are priced on their own stack. Use the LatAm developer cost calculator to compare by country and seniority.

    Nearshore in LATAM

    Latin America works in U.S. hours, 0 to 4 hours from Eastern time. For a mobile team that matters on the days with the most risk: a store rejection, a signing failure the night before a launch, a crash spike after an update. Our network includes more than 1,300 engineers with Xamarin or .NET MAUI in their work history, about half of them senior or above, inside a much larger .NET pool. For a broader view of mobile hiring with BEON.tech, see our mobile app development page, and for the region, our guide to hiring Latin American developers.
