Examples
Composing an EF Core data layer in Savvy I/O requires three registrations: AddEfCoreDataSource to bind the DbContext and IEfCoreDataSource, AddEfCoreDataStore for generic read/write stores, and AddEfCoreRepository for aggregate-scoped repositories. Each registration takes the concrete type as a type argument, and the data source must be registered first because stores and repositories depend on it. The example resolves both a repository and a data store from the built service provider to confirm the bindings are correct.
