Metalama is a Roslyn-based framework for on-the-fly code generation and validation in C#.
Using Metalama, you can:
- Reduce boilerplate by generating it dynamically during compilation. Your source code remains crystal-clear.
- Verify code in real time against architecture, patterns, and conventions. No need to wait for code reviews.
- Provide coding assistance to your team with customized feedback and suggestions.
- Do it by your rules. Automate your own implementation patterns and architecture guidelines.
For more information, see the Metalama website or Metalama documentation.
About this package
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 allow us to transform the syntax trees. If you need to reference Metalama without replacing the compiler, use the Metalama.Framework.Redist package.
