The Metalama.Framework package is the principal package of Metalama. Reference this package if you want to use Metalama in your code.

Referencing this package replaces the compiler with Metalama.Compiler, a shallow fork of Roslyn that adds an extension point to transform the syntax trees.

What is Metalama?

Metalama is a modern, Roslyn-based meta-programming framework C# with focus on aspect-oriented programmning, code generation and code validation.

It is an extension of the Microsoft "Roslyn" C# compiler that allows you to automatically transform your source code at build time or design time based on encapsulated code transformations called aspects. Metalama can be used for aspect-oriented programming, code generation, or architecture validation.

Metalama is intended to replace the MSIL-based stack that is now the foundation of PostSharp.
