Namespace Metalama.Framework.Introspection

Overview

This namespace reveals intermediate details of the compilation process, such as the list of aspect classes, aspect instances, advice, transformations, and diagnostics.

This namespace proves useful when troubleshooting an aspect, a fabric, or a set of aspects. It provides details that are not readily apparent from the compilation output.

To begin with this namespace, load your C# project or solution using the Metalama.Framework.Workspaces namespace or with the LINQPad driver. Refer to Inspecting a project using LINQPad for more information.

The entry point of this namespace is the IIntrospectionCompilationDetails interface. This interface is implemented by the Workspace and Project classes.

For example, the following query returns all aspect instances in a project:

workspace.GetProject("Metalama.Samples.Log4", "net8.0").AspectInstances
