Top 23 C# Android Projects

  1. Avalonia

    Develop Desktop, Embedded, Mobile and WebAssembly apps with C# and XAML. The most popular .NET UI client technology

    Project mention: The History and Legacy of Visual Basic | news.ycombinator.com | 2025-05-11

    Check out https://avaloniaui.net as well. It's basically a cross-platform reimplementation of WPF. It's not quite as simple as C#+WinForms or Lazarus+LCL because you don't get drag-and-drop UI designer, and you need to write markup by hand (albeit with live preview). But unlike HTML, it's actually designed for desktop UI apps from the get go, so it's much easier to write for anything non-trivial. And you can still write "quick and dirty" GUI code by directly connecting event handlers to buttons and updating values etc in it, ignoring data bindings and other more advanced facilities.

  2. InfluxDB

    InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

  3. Introducing .NET Multi-platform App UI (MAUI)

    Project mention: .NET MAUI Authentication on Windows: The OpenID Connect Challenge | dev.to | 2025-05-06

    You know, I'm not the only one surprised by this issue. If you take a look at the long threads around this issue, you can see many developers are complaining about the missing support for a very common feature such as authentication in Microsoft's own operating system!

  4. Mono

    Mono open source ECMA CLI, C# and .NET implementation.

    Project mention: The Windows Subsystem for Linux is now open source | news.ycombinator.com | 2025-05-19

    > whereas Microsoft is actively sabotaging wine

    Do you have a link to where I can read more about this? My understanding is that Microsoft saw Wine as inconsequential to their business, even offloading the Mono runtime to them [1] when they dropped support for it.

  5. Uno Platform

    Open-source platform for building cross-platform native Mobile, Web, Desktop and Embedded apps quickly. Create rich, C#/XAML, single-codebase apps from any IDE. Hot Reload included! 90m+ NuGet Downloads!!

    Project mention: Any devs actually getting a leg up using AI tools? | dev.to | 2025-02-21

    As-is today, AI tools provide some productivity gains. However, they are not replacements for experienced developers. At Uno Platform we are investing in tools which make developers productive within their current environments, such as Hot Design. Also, we are keeping a close eye and thinking of these useful scenarios to apply AI to, as we don’t believe just adding a simple LLM to it will actually add value. So, stay tuned to our blogs and Dev.to account as there is more goodness coming on this topic.

  6. ReactiveUI

    An advanced, composable, functional reactive model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming. ReactiveUI allows you to abstract mutable state away from your user interfaces, express the idea around a feature in one readable place and improve the testability of your application.
