List of NuGet packages

Metalama comprises several NuGet packages. However, some are only used for testing or troubleshooting and should not be included in your public packages.

Package list

Package Name	Scenarios	Description
Metalama.Framework.Redist	Run-Time Execution	This is the only package required to execute code built with Metalama. It does not contain or reference the assets required to build with Metalama.
Metalama.Framework	Compiling, Testing, Introspection	This is the typical top-level package for a project that defines Metalama aspects.
Metalama.Compiler	Compiling	This package replaces Microsoft's C# compiler (Roslyn) with Metalama's own fork.
Metalama.Compiler.Sdk	Compiling	This package defines the extensibility API of `Metalama.Compiler`.
Metalama.Framework.Sdk	Compiling	This package defines the low-level extensibility API of `Metalama.Framework` (extensions using the Roslyn API).
Metalama.Testing.AspectTesting	Testing	This is the top-level package for test projects. It references `Metalama.Framework` but inhibits most of its behaviors. See Testing the aspect's code generation and error reporting.
Metalama.Framework.Engine	Testing, Introspection	This is the principal implementation assembly of Metalama. It is required by the testing and introspection packages. However, it should not be used directly as there is no forward compatibility promise for this package.
Metalama.Framework.Introspection	Introspection	This package allows querying the code model representing the output of the Metalama process.
Metalama.Framework.Workspaces	Introspection	This package allows any application to load a Visual Studio project or solution and to represent its code model and the Introspection of the Metalama process.
