.NET MAUI vs. Xamarin: What's the Best Cross-Platform Framework Today?
You want to build a mobile app.
But you don't want to build it twice — once for iPhone users and once for Android users. That would double your budget, double your development time, and double your headaches.
So someone on your team — or maybe a developer you spoke to — mentioned two options: .NET MAUI and Xamarin.
Both promise the same thing: write your code once, and it runs on multiple platforms. Sounds great. But which one should you actually use in 2026?
If you've been going back and forth on this, you're not alone. It's one of the most common questions businesses ask when planning a mobile or cross-platform application. And the answer isn't just "pick the newer one" — there's more to it than that.
Let's break it down in plain language, so you can make a confident decision.
A Quick Backstory
To understand where we are today, it helps to know where we came from.
Xamarin was created by a company called Xamarin Inc. back in 2011. Microsoft bought it in 2016 and made it free for developers. For years, it was the go-to choice for businesses that wanted to build cross-platform mobile apps using C# and the .NET ecosystem.
It was widely adopted, well-supported, and many businesses built serious products on it.
Then Microsoft announced something big.
In 2022, they introduced .NET MAUI — which stands for Multi-platform App UI. It was positioned as the next generation of Xamarin. The spiritual successor. The upgrade.
And in May 2024, Microsoft officially ended support for Xamarin. No more updates. No more security patches. No more official help.
That changed everything.
What Is .NET MAUI?
.NET MAUI is Microsoft's modern framework for building cross-platform applications using C# and .NET. With a single codebase, you can build apps that run on:
Android
iOS
macOS
Windows
Yes, you read that right — not just mobile. .NET MAUI lets you target desktop platforms too, which Xamarin couldn't do natively. This is one of the biggest upgrades it brings to the table.
It's built into the unified .NET platform — meaning it works seamlessly with the same tools, libraries, and ecosystem that .NET developers already use for web and backend development.
What Was Xamarin?
Xamarin was Microsoft's previous cross-platform framework, primarily focused on mobile — Android and iOS.
It came in two flavours:
Xamarin.Forms — a shared UI framework where you write one UI for all platforms. This is the part that .NET MAUI directly replaces and improves.
Xamarin.Native (Xamarin.Android / Xamarin.iOS) — where you write platform-specific UI but share the business logic. More control, but more work.
For its time, Xamarin was excellent. But with official support now ended, continuing to build new projects on Xamarin is like building a house on a foundation that's slowly cracking. It'll hold for now — but not forever.
Let's look at what really matters when you're making a business decision.
1. Platform Support
Xamarin: Android and iOS only (mobile-focused).
.NET MAUI: Android, iOS, macOS, and Windows — all from a single project.
This alone is a significant shift. If your business needs an app that works on both mobile and desktop, MAUI handles it in one codebase. With Xamarin, you'd need separate projects for desktop platforms.
For businesses that want to give employees a tool that works on their phone and their laptop — think field service apps, internal management tools, or sales apps — .NET MAUI is the clear winner.
Winner: .NET MAUI
2. Performance
Xamarin performed reasonably well, but it had a known issue: startup times could be slow, and apps sometimes felt a little heavy compared to fully native apps.
.NET MAUI addresses this directly. It uses newer .NET runtime improvements and has better startup performance out of the box. It also supports ahead-of-time (AOT) compilation, which means the app is partially compiled before it runs — making it faster and leaner on device.
Real-world results vary by project, but .NET MAUI apps generally feel snappier and more responsive than their Xamarin equivalents.
Winner: .NET MAUI
3. UI and Design Flexibility
This is an area where .NET MAUI made meaningful improvements.
Xamarin.Forms had a reputation for UI limitations. Getting pixel-perfect designs or highly customised interfaces sometimes required a lot of workarounds. Developers often had to drop down to platform-specific code just to achieve something that should have been simple.
.NET MAUI introduced a new rendering architecture, giving developers more direct control over how UI elements are drawn on each platform. Custom controls are easier to build. Platform-specific customisations are more straightforward. And the overall design capability is significantly better.
If your app needs to look great and feel native on every platform, MAUI gives you more tools to make that happen.
Winner: .NET MAUI
4. Developer Experience and Tooling
Xamarin had decent tooling, but it existed as a kind of add-on to Visual Studio. Over time, managing dependencies, updating NuGet packages, and dealing with platform-specific build issues became a common frustration for developers.
.NET MAUI is built directly into the unified .NET ecosystem. It uses the same SDK, the same CLI tools, the same dependency management, and the same project structure as other .NET projects. For a C# developer who also does backend or web work, switching between a MAUI app and an ASP.NET API feels seamless.
This is especially relevant for teams using custom .NET development services in India — where developers often work across multiple parts of a project. When the mobile layer uses the same tools as the backend, collaboration gets easier and development gets faster.
Winner: .NET MAUI
5. Community and Long-Term Support
Xamarin's community was large and active for years. There are countless tutorials, Stack Overflow answers, GitHub repositories, and blog posts about it. That's actually still useful — a lot of the patterns from Xamarin carry over to MAUI.
But the community has clearly moved on. New content, new packages, and new discussions are almost entirely focused on .NET MAUI now. Microsoft is investing heavily in it, and the ecosystem is growing fast.
Xamarin gets no new features. No security updates. No official support. If you hit a problem today, you're largely on your own.
.NET MAUI has full Microsoft backing, active development, regular releases, and a growing community of developers building with it every day.
Winner: .NET MAUI
6. Migration from Xamarin to MAUI
Here's a practical question many businesses are asking right now: We have an existing Xamarin app. What do we do?
The honest answer is: migration takes effort, but it's very doable — and it's necessary.
Microsoft has published official migration guides, and many of the concepts, patterns, and C# code from Xamarin carries over well. The UI layer needs the most attention, but the business logic, data access code, and API integrations often migrate with minimal changes.
The longer you wait to migrate, the harder it gets. As Xamarin ages without updates, security risks increase and compatibility with newer versions of Android and iOS will eventually break.
If you have a Xamarin app, start planning the migration now. Work with a team experienced in custom .NET development services in India who can assess your existing codebase and build a migration plan that doesn't disrupt your users.
Is There Any Case Left for Xamarin?
Let's be fair here.
If your business already has a Xamarin app that's running fine and you don't have the budget to migrate right now, it won't fall apart overnight. You have some runway.
But for any new project starting today? There is no good reason to build on Xamarin. None. Microsoft ended support. The community has moved on. You'd be starting with a framework that has no future.
Even businesses that have older Xamarin apps are actively making plans to move to MAUI. The question for them isn't whether to migrate — it's when and how.
Who Should Use .NET MAUI?
.NET MAUI is a great fit for:
Businesses building new mobile apps — If you're starting fresh and want iOS and Android coverage from one codebase, MAUI is the way to go.
Companies that need mobile + desktop — If your workforce uses both phones and Windows computers, MAUI lets you cover both with one development investment.
Teams already using .NET — If your backend is built with ASP.NET or your internal tools use C#, extending into mobile with MAUI keeps everything in one cohesive stack.
Enterprises replacing legacy Xamarin apps — Migration to MAUI is the logical and responsible next step for any business currently running on Xamarin.
Businesses outsourcing development — Partnering with a company that offers custom .NET development services in India gives you access to experienced MAUI developers at competitive rates, with the full backing of the Microsoft ecosystem.
A Real-World Scenario
Imagine a field service company. Their technicians travel to job sites, need to log work orders on their phones, and then managers review everything on Windows laptops back at the office.
With .NET MAUI, a single app — built once — works on both the technician's Android phone and the manager's Windows desktop. The same codebase. The same UI logic. The same data layer connects to the same backend API.
With Xamarin? You'd need separate projects for mobile and desktop, more development time, and more ongoing maintenance. And you'd be doing it all on a framework that Microsoft no longer supports.
The choice becomes pretty obvious.
The Verdict
There's really no competition here in 2026.
.NET MAUI wins — clearly and completely.
Xamarin was a great framework for its time, and it served thousands of businesses well. But that time has passed. Microsoft has moved on. The developer community has moved on. And if your business wants to build cross-platform apps that are fast, secure, maintainable, and supported for years to come, you need to move on too.
Whether you're starting a brand new project or looking to migrate an existing Xamarin application, .NET MAUI is the right investment — both technically and commercially.
