Examples

Create a projection

public class Projection : IProjection<Projection, Guid>
{
    public Projection(Guid id, ETag etag)
    {
        Id = id;
        ETag = etag;
    }
    public Guid Id { get; }

    public ETag ETag { get; }

    public Projection WithETag(ETag etag) => new Projection(Id, etag);
}

Create a Repository for the projection

public interface IProjectionRepository : IGenericMoldingRepository<Projection, Guid>
{
    Task<IReadOnlyCollection<...>> OtherMethods(...);
}

public class ProjectionRepository : GenericProjectionRepository<Projection>, IProjectionRepository
{
    public ProjectionRepository(DatabaseSessionProvider sessionProvider, ILog log) : base(sessionProvider, log) {}

    public Task<IReadOnlyCollection<...>>>> OtherMethods(...)
		=> Query(model => model.Cargo...);
}

Create a Repository for entities which expire (Deleted after a specified date/time)

public class ProjectionRepository : GenericProjectionRepository<Projection>, IProjectionRepository
{
    public ProjectionRepository(DatabaseSessionProvider sessionProvider, ILog log, ITimeProvider timeProvider) : base(sessionProvider, log, AdvancedOptions<Projection>.Empty.WithExpiration(projection => timeProvider.Get().AddDays(10))) {}
}
