Tolitech.Infrastructure.Persistence.EntityFrameworkCore.Specifications

A .NET library providing a foundational implementation of the Specification pattern for Entity Framework Core. It enables flexible, reusable, and composable queries using specifications, supporting advanced filtering, dynamic ordering, projections, and pagination.

Features

  • Specification pattern for EF Core
  • Generic repository base with async methods
  • Dynamic ordering by property path (string)
  • Projections and advanced query composition
  • Paging, includes, and split queries support

Installation

Add the NuGet package to your project:

dotnet add package Tolitech.Infrastructure.Persistence.EntityFrameworkCore.Specifications

Getting Started

1. Create a Specification

Define a specification by inheriting from Specification<TEntity>:

using Tolitech.Specifications;

public class ActiveCustomersSpecification : Specification<Customer>
{
    public ActiveCustomersSpecification()
    {
        Where(c => c.IsActive);
        OrderBy(c => c.Name);
        Take(10); // Paging example
    }
}

2. Use the Repository

Inherit from the provided Repository<TEntity> base class:

using Tolitech.Infrastructure.Persistence.EntityFrameworkCore.Specifications;

public class CustomerRepository : Repository<Customer>
{
    public CustomerRepository(MyDbContext dbContext) : base(dbContext) { }
}

3. Query with Specifications

var spec = new ActiveCustomersSpecification();
var customers = await customerRepository.ToListAsync(spec, cancellationToken);

4. Projections and Dynamic Ordering

// Projection
var names = await customerRepository.ToListAsync(
    spec,
    c => c.Name,
    cancellationToken);

// Dynamic ordering by string
spec.OrderByAsString.Add("Name:DESC");

5. Advanced: Includes, Paging, Split Queries

public class CustomerWithOrdersSpecification : Specification<Customer>
{
    public CustomerWithOrdersSpecification()
    {
        Where(c => c.IsActive);
        Include(c => c.Orders);
        EnableSplitQuery();
        Skip(10);
        Take(10);
    }
}

Tolitech.Infrastructure.Persistence.EntityFrameworkCore.Specifications brings powerful, maintainable, and reusable querying to your EF Core repositories.
