EfTune

EfTune is a lightweight, extensible EF Core enhancement toolkit that brings interceptors, UTC conversion, auditing, value object support, domain event dispatching, soft delete handling, and more — all designed with clean architecture and modular design in mind.

"Enhance EF Core without the bloat. Just tune what you need."

Features

• ISaveChangesInterceptor-based composite pipeline
• Automatic UTC Conversion with [AutoUtc] support
• Audit Fields (CreatedAt, UpdatedAt, CreatedBy, UpdatedBy)
• Soft Delete Interceptor + Global Query Filters
• Value Object Conversion (HasConversion<TValueObject, Primitive>)
• Seed Helpers (SeedIfEmpty, SeedFromEnum)
• Global Query Filters for interfaces like ITenantScoped
• RowVersion / Concurrency Token Automation
• Domain Event Dispatcher with outbox compatibility
• Minimal setup, maximum flexibility

---

Installation

dotnet add package Moongazing.EfTune
 Setup

In your Program.cs or Startup.cs:

services.AddEfTune(x => x
    .EnableUtc()
    .EnableAudit()
    .EnableSoftDelete()
    .EnableDomainEvents()
);

If you're using domain events:

services.AddScoped<IDomainEventPublisher, YourEventPublisher>();

 Interfaces
IAuditableEntity

public interface IAuditableEntity
{
    DateTime CreatedAt { get; set; }
    DateTime UpdatedAt { get; set; }
    string? CreatedBy { get; set; }
    string? UpdatedBy { get; set; }
}

ISoftDeletable

public interface ISoftDeletable
{
    bool IsDeleted { get; set; }
}

IHasRowVersion

public interface IHasRowVersion
{
    byte[] RowVersion { get; set; }
}

IDomainEvent & IHasDomainEvents

public interface IDomainEvent
{
    DateTime OccurredOn { get; }
}

public interface IHasDomainEvents
{
    List<IDomainEvent> DomainEvents { get; }
    void ClearDomainEvents() => DomainEvents.Clear();
}

 ModelBuilder Extensions

In your DbContext:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder
        .UseSoftDelete()
        .UseGlobalFilter<ITenantScoped>(e => e.TenantId == tenantId)
        .UseConcurrencyTokens();
}

 Value Object Mapping

modelBuilder.Entity<User>()
    .HasSimpleValueObjectConversion(u => u.Email);

Or custom:

modelBuilder.Entity<User>()
    .HasValueObjectConversion(
        u => u.Email,
        vo => vo.Value,
        val => new Email(val)
    );

 Seeding

await db.SeedIfEmptyAsync(new[]
{
    new Category { Id = 1, Name = "Books" }
});

await db.SeedFromEnumAsync<RoleType, Role>(e => new Role
{
    Id = (int)(object)e,
    Name = e.ToString()
});

 Domain Events
Entity

public class Order : IHasDomainEvents
{
    public List<IDomainEvent> DomainEvents { get; } = new();
    public void AddCreatedEvent() => DomainEvents.Add(new OrderCreated(Id));
}

Event

public record OrderCreated(Guid OrderId) : IDomainEvent
{
    public DateTime OccurredOn { get; } = DateTime.UtcNow;
}

Publisher (example)

public class ConsolePublisher : IDomainEventPublisher
{
    public Task PublishAsync(IDomainEvent @event, CancellationToken ct = default)
    {
        Console.WriteLine($"Published: {@event.GetType().Name}");
        return Task.CompletedTask;
    }
}

 Philosophy

EfTune is built with:

    Clean architecture principles

    Modularity & composability

    Convention over configuration

    Production-readiness with minimal friction
