Capability Catalog
Capabilities are pluggable pieces of functionality for your applications. Plug them in and swap them out whenever you want.
Every capability consists of a standard API and one or more swappable plugins called capability providers. Learn more about capabilities, providers, interfaces, and other core concepts in the Platform Guide.
