Top .NET Micro Framework for Linux Alternatives for Embedded Development
.NET Micro Framework for Linux (NETMF Linux) served as a valuable sample porting code, offering complete OS facilities for embedded ARM architecture Linux boards like SystemBase's Eddy series. While NETMF Linux provided a solid foundation for those looking to port code across various architectures with the right cross-toolchain, the evolving landscape of embedded and cross-platform development means many are now seeking robust and actively supported .NET Micro Framework for Linux alternatives.
Exploring the Best .NET Micro Framework for Linux Alternatives
Whether you're looking for broader platform support, more modern features, or a thriving open-source community, there are excellent options available that can pick up where NETMF Linux left off. Here are some of the top contenders:

Mono
Mono is a free and open-source project that aims to create an Ecma standard compliant .NET Framework-compatible set of tools. As a cross-platform solution available on Mac, Windows, Linux, and BSD, Mono is an excellent .NET Micro Framework for Linux alternative for developers who need to run .NET applications on various operating systems, leveraging its robust developer tools and extensive community support.

.NET Framework
.NET Framework is a free, open-source, and cross-platform developer platform primarily for building applications on Windows. While NETMF Linux focused on embedded Linux, .NET Framework serves as a foundational platform for a wide array of applications, making it a powerful .NET Micro Framework for Linux alternative for those whose projects might extend beyond embedded systems into more traditional desktop or server-side development, offering comprehensive developer tools.

.NET Core
.NET Core is a cross-platform, free, and open-source managed software framework, similar to .NET Framework, that includes CoreCLR, a complete cross-platform runtime. As a truly cross-platform solution supporting Mac, Windows, and Linux, .NET Core stands out as a strong .NET Micro Framework for Linux alternative, especially for modern embedded and IoT projects requiring a robust runtime, command-line interface, and the ability to produce native applications.

CrossBrowdy
CrossBrowdy is a multimedia JavaScript framework designed to create real cross-platform and hybrid game engines, games, emulators, multimedia libraries, and applications for the Web. While not a direct .NET competitor in terms of language, its focus on cross-platform development and progressive web app capabilities makes it an interesting .NET Micro Framework for Linux alternative for projects where the embedded device can serve web content or run browser-based applications, especially in gaming or interactive multimedia contexts.

Motti.NET (Programming Language)
Motti.NET (mottidotnet) is an advanced programming language with visual and programming features, described as very stable. Available as Free Personal, $, $ $, and Open Source, with support for Windows and Web platforms, Motti.NET presents a unique programming language alternative. While it doesn't directly replace the embedded Linux focus of .NET Micro Framework, its advanced features and stability might appeal to developers looking for a different approach to application development, potentially for components that interface with embedded systems.
Choosing the best .NET Micro Framework for Linux alternative depends heavily on your specific project requirements, target hardware, and development preferences. By exploring these powerful and versatile options, you can find the perfect fit to continue building innovative embedded and cross-platform solutions.
