Making aspects configurable
Complex and widely-used aspects often require a centralized, project-wide method for configuring their compile-time behavior. Implementing a configuration for aspects provides the following benefits:
Centralized aspect options: A configuration API allows the entire project, namespaces, or class families to be configured from a single location. Without a configuration API, users must supply the configuration each time a custom attribute is used.
Run-time performance: Considering compile-time options, your aspect can generate optimal run-time code, resulting in higher run-time performance of your application.
There are two complementary mechanisms for configuration: the configuration API and MSBuild properties.
Compile-time configuration has significantly changed with Metalama 2023.4. If you are looking for the previous configuration API, see Exposing configuration (before v2023.4)
