Class EfCoreRepository<TEntity, TKey, TMarker>

Namespace: Savvyio.Extensions.DependencyInjection.EFCore

Assembly: Savvyio.Extensions.DependencyInjection.EFCore.dll

Provides a default implementation of the IPersistentRepository<TEntity, TKey, TMarker> interface to support multiple implementations that serves as an abstraction layer before the actual I/O communication with a source of data using Microsoft Entity Framework Core.

public class EfCoreRepository<TEntity, TKey, TMarker> : EfCoreRepository<TEntity, TKey>, IPersistentRepository<TEntity, TKey, TMarker>, IPersistentRepository<TEntity, TKey>, IWritableRepository<TEntity, TKey, TMarker>, IWritableRepository<TEntity, TKey>, IReadableRepository<TEntity, TKey, TMarker>, IReadableRepository<TEntity, TKey>, ISearchableRepository<TEntity, TKey, TMarker>, ISearchableRepository<TEntity, TKey>, IDeletableRepository<TEntity, TKey, TMarker>, IRepository<TEntity, TKey, TMarker>, IDependencyInjectionMarker<TMarker>, IDeletableRepository<TEntity, TKey>, IRepository<TEntity, TKey> where TEntity : class, IIdentity<TKey>

Type Parameters

TEntity: The type of the entity.
TKey: The type of the key that uniquely identifies the entity.
TMarker: The type used to mark the implementation that this repository represents. Optimized for Microsoft Dependency Injection.

Examples

The DI-registered EfCoreRepository<TEntity, TKey, TContext> resolves as IRepository<TEntity, TKey> when registered via AddEfCoreRepository. The data source registered by AddEfCoreDataSource provides the context. The example registers and resolves the repository to verify the complete EF Core repository wiring.
