Enigmatry.Entry.EntityFramework 9.1.1-preview.4

Entity Framework Core Extensions

A library that provides extensions and utilities for working with Entity Framework Core, enhancing the ORM capabilities with additional features and patterns.

Intended Usage

Use this library to implement common Entity Framework Core patterns and extensions, such as repositories, unit of work, auditing, and soft delete functionality.

Installation

Add the package to your project:

dotnet add package Enigmatry.Entry.EntityFramework

Usage Example

Creating a repository:

using Enigmatry.Entry.Core.Entities;
using Enigmatry.Entry.EntityFramework;
using Microsoft.EntityFrameworkCore;

// Define an entity
public class Customer : EntityWithTypedId<Guid>
{
    public string Name { get; set; } = string.Empty;
    public string Email { get; set; } = string.Empty;
    public bool IsActive { get; set; }
}

// Create a DbContext
public class ApplicationDbContext : BaseDbContext
{
    public DbSet<Customer> Customers { get; set; } = default!;
    
    public ApplicationDbContext(DbContextOptions options, EntitiesDbContextOptions entitiesDbContextOptions)
        : base(entitiesDbContextOptions, options)
    {
    }
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        
        // Model builder is configured through base class
    }
}

// Use the repository pattern
public interface ICustomerRepository : IRepository<Customer, Guid>
{
    Task<Customer?> FindByEmailAsync(string email);
}

public class CustomerRepository : EntityFrameworkRepository<Customer, Guid>, ICustomerRepository
{
    public CustomerRepository(ApplicationDbContext dbContext)
        : base(dbContext)
    {
    }
    
    public async Task<Customer?> FindByEmailAsync(string email)
    {
        return await DbSet
            .FirstOrDefaultAsync(c => c.Email == email && c.IsActive);
    }
}

Dependency Injection Example

Register Entity Framework services:

using Enigmatry.Entry.Core.Data;
using Enigmatry.Entry.EntityFramework;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // Configure EntitiesDbContextOptions
        var entitiesOptions = new EntitiesDbContextOptions
        {
            ConfigurationAssembly = typeof(Customer).Assembly
        };
        services.AddSingleton(entitiesOptions);
        
        // Register DbContext
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        
        // Register repositories
        services.AddScoped<ICustomerRepository, CustomerRepository>();
        
        // Add unit of work
        services.AddScoped<IUnitOfWork, EntityFrameworkUnitOfWork>();
        
        // Register DbContext as the concrete DbContext implementation for the unit of work
        services.AddScoped<DbContext>(sp => sp.GetRequiredService<ApplicationDbContext>());
    }
}
