DKNet Framework

A suite of 28 independent .NET 10 NuGet packages for building enterprise applications around Domain-Driven Design and Onion Architecture.

✨ Why use it?

• Take only what your DbContext or API needs. Each package is opt-in and registers itself: there is no AddDKNet() and no package that only aggregates others.
• One repository for every entity. DKNet.EfCore.Specifications gives you one injected IRepositorySpec that takes a reusable specification, instead of a hand-rolled repository per entity.
• Cross-cutting rules stay out of domain code. Domain events, audit logs, row-level data authorization and column encryption attach to the DbContext through the SaveChanges hook pipeline or a value converter.
• CQRS without MediatR. DKNet.SlimBus.Extensions builds commands, queries and event consumers on SlimMessageBus, saves the DbContext after a successful write and forwards domain events onto the bus.
• ASP.NET Core and service glue included. Idempotent endpoints, startup background tasks, minimal-API endpoint groups, blob storage adapters, PDF generation and .NET Aspire integrations ship as their own packages.

🚀 Quick Start

Use a .NET 10 console project. Install the packages, then replace Program.cs with the example.

dotnet new console -f net10.0 -n EfCoreDemo
cd EfCoreDemo
dotnet add package DKNet.EfCore.Specifications
dotnet add package Microsoft.EntityFrameworkCore.Sqlite --version 10.0.12

using DKNet.EfCore.Specifications;
using DKNet.EfCore.Specifications.Definitions;
using DKNet.EfCore.Specifications.Extensions;
using DKNet.EfCore.Specifications.Repositories;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;

using var connection = new Microsoft.Data.Sqlite.SqliteConnection("Data Source=:memory:");
connection.Open();
var services = new ServiceCollection();
services.AddDbContext<DemoDb>(o => o.UseSqlite(connection));
services.AddSpecRepo<DemoDb>();
using var provider = services.BuildServiceProvider();
using var scope = provider.CreateScope();
await using var db = scope.ServiceProvider.GetRequiredService<DemoDb>();
await db.Database.EnsureCreatedAsync();
var repo = scope.ServiceProvider.GetRequiredService<IRepositorySpec>();
await repo.AddRangeAsync(new[]
{
    new Product { Name = "Coffee", Price = 12 },
    new Product { Name = "Tea", Price = 6 }
});
await repo.SaveChangesAsync();
var rows = await repo.ToListAsync(new MinimumPrice(10));
Console.WriteLine(rows.Single().Name); // Coffee

public sealed class DemoDb(DbContextOptions<DemoDb> options) : DbContext(options)
{
    public DbSet<Product> Products => Set<Product>();
}
public sealed class Product
{
    public int Id { get; set; }
    public string Name { get; set; } = "";
    public int Price { get; set; }
}
public sealed class MinimumPrice : Specification<Product>
{
    public MinimumPrice(int minimum)
    {
        WithFilter(p => p.Price >= minimum);
        AddOrderBy(p => p.Id);
        AsNoTracking();
    }
}

Run with dotnet run. Prints Coffee.
