Examples

The DI-registered EfCoreDataSource<TContext> is the concrete IEfCoreDataSource bound by AddEfCoreDataSource. Resolve it as IEfCoreDataSource to access the DbContext factory or pass it to EF Core repositories. The example registers the data source with an in-memory provider and resolves it from the service provider.
