We’re excited to announce that Metalama, the most advanced meta-programming framework for C#, is now open source! Released under the permissive MIT license, Metalama empowers .NET developers with a simple, innovative, and powerful approach to code generation, architecture validation, and aspect-oriented programming.
As we returned from the winter break, we hit the ground running by launching Metalama and PostSharp 2025.0. But that wasn’t all—after careful consideration and experimentation, we’re thrilled to share some groundbreaking news: Metalama is going open-source!
Godot is an amazing open-source game engine that provides developers with the tools to build games efficiently. While GDScript is Godot’s native language, many developers prefer to use C# for its rich ecosystem and the ability to leverage third-party libraries. One such library is Metalama, a powerful metaprogramming framework that can streamline repetitive or error-prone tasks.
We’re thrilled to announce that Metalama, the most complete and innovative meta-programming framework for .NET, will soon become a free and open-source project. This is a major milestone for us and the .NET community, and we’re excited to share our plans and gather your feedback as we move forward.
Metalama 2025.0 is now generally available! This release supports C# 13 and .NET 9, adds significant enhancements to the aspect framework, and boosts performance substantially.
