[prochan2]

We've just released Metalama 2023.4.2-preview, which includes all fixes and enhancements from 2023.4.1-preview and 2023.3.6-rc in addition to the following changes.

New Features

• New Metalama.Framework.Options namespace: a new framework for hierarchical options of aspects. See the API doc. The conceptual doc will come later.
• Annotations: a facility to add and query custom annotations. See IAnnotation, IAdviceFactory.AddAnnotation and declaration.Enhancements().GetAnnotations.

Improved

New APIs:

• IMemberOrNamedType.GetBase extension method: gets the base type or overridden member.
• IAttribute.TryConstruct extension method: creates a CLR instance of a compile-time custom attribute.
• ICompilation.GetAllAttributesOfType: gets all attributes of a given type in a project.
• IMemberOrNamedType.Definition: navigates to the generic definition.
• LocationExtensions.ToDiagnosticLocation( this Location? location ): converts a Roslyn Location into a Metalama IDiagnosticLocation.

Changed behavior

• For external namespaces, the ContainingDeclaration of the namespace now returns the declaring assembly instead of the current compilation

Breaking changes

Metalama.Extensions.DependencyInjection

• The DependencyProperties record constructor has changed.
• The framework should now be configured with the new hierarchical options framework. The object DependencyInjectionOptions has completely changed. It may not be the final design.

Fixed

• Fixed: INamespace: Conflicts when several assemblies contributed to the same namespace.
• Fixed: Attributes may be incorrectly indexed in case of using XX = YY.
• Fixed: Warning "Analyzer assembly was disabled because it references Roslyn 4.7.0".
• Fixed: Compile-time interface with a base interface that has init-only setter results in an assertion failure.
• Fixed: Template compiler: init accessors of aspect classes should not be changed into set accessors.
• Fixed: Enhancements().HasAspect does not report inherited aspects.
