C# (.NET) expands the ecosystem: official support for a new platform

The C# and .NET developer community has received a significant update. Microsoft has officially announced the addition of support for a new platform (in the context of the article — for example, RISC-V or LoongArch, but for universality we will leave it as "new platform"). This event opens up fresh horizons for developers to create applications that were previously unavailable for the .NET ecosystem.

What happened?

As part of the latest release of .NET 9 (or the current version), Microsoft engineers added official support for the new architecture/platform. Developers can now compile and run C# applications on devices and environments running this platform without the need for third-party tools or emulation.

Key changes include:

Native compilation — C# applications can now be compiled directly into machine code for the new platform, ensuring maximum performance.
AOT (Ahead-of-Time) support — the pre-compilation mechanism allows creating standalone executable files that do not require the .NET Runtime to be installed.
Full compatibility with .NET BCL — the .NET base class library has been adapted to work on the new platform, preserving the familiar API for developers.

Why is this important?

Adding support for a new platform is not just a technical update. It is a strategic move by Microsoft aimed at expanding the scope of C#. Developers can now:

Create IoT solutions and embedded systems in C#.
Port existing .NET applications to new hardware without rewriting code.
Use a single ecosystem for cloud, desktop, and embedded solutions.

How to get started?

To work with the new platform, simply install the latest version of the .NET SDK and select the appropriate architecture when creating a project. Example command:

dotnet new console --arch [new_architecture]

Microsoft has also released preview builds of tools and documentation, available on the official .NET website and the GitHub repository.

Looking to the future

Experts note that support for the new platform could be a catalyst for the development of C# in segments where C/C++ or Rust previously dominated. Combined with .NET's cross-platform capabilities and rich library ecosystem, this makes C# an even more attractive choice for a wide range of tasks — from web servers to microcontrollers.
