RepositoryKit.EntityFramework

Entity Framework Core Implementation for RepositoryKit

</div>

📦 Package

This package contains the Entity Framework Core based implementation of the RepositoryKit abstractions.

✅ Implementations

🚀 Usage Examples

1. Register in DI (Startup or Program.cs)

// Register DbContext and RepositoryKit services
builder.Services.AddDbContext<SampleDbContext>(opt => opt.UseInMemoryDatabase("SampleDb"));
builder.Services.AddScoped(typeof(IUnitOfWork<>), typeof(EfUnitOfWork<>));
builder.Services.AddSingleton<IUnitOfWorkManager, EfUnitOfWorkManager>();

// Custom repository registration (interface-based)
builder.Services.AddScoped<IProductRepository, ProductRepository>();

2. Basic Repository & UnitOfWork Usage (Minimal API)

app.MapPost("/products", async (IUnitOfWork<SampleDbContext> uow, Product product) =>
{
    var repo = uow.GetRepository<Product>();
    await repo.AddAsync(product);
    await uow.SaveChangesAsync();
    return Results.Created($"/products/{product.Id}", product);
});

3. Custom Repository Inheritance & Usage

Custom Repository Interface and Implementation

public interface IProductRepository : IRepository<Product>
{
    Task<List<Product>> GetExpensiveProductsAsync(decimal minPrice);
}

public class ProductRepository : EfRepository<Product, SampleDbContext>, IProductRepository
{
    public ProductRepository(SampleDbContext context) : base(context) { }

    public async Task<List<Product>> GetExpensiveProductsAsync(decimal minPrice)
    {
        return await _dbSet.Where(p => p.Price > minPrice).ToListAsync();
    }
}

Endpoint Usage

app.MapGet("/products/expensive", async (IProductRepository repo, decimal minPrice) =>
{
    var expensive = await repo.GetExpensiveProductsAsync(minPrice);
    return Results.Ok(expensive);
});

4. Multiple Contexts with IUnitOfWorkManager

app.MapGet("/multi-context-demo", (IUnitOfWorkManager uowManager) =>
{
    var uow = uowManager.GetUnitOfWork<SampleDbContext>();
    var repo = uow.GetRepository<Product>();
    // Use repo as needed...
});

🚨 Exception Handling

All repository and unit of work operations wrap provider or database exceptions with the standard RepositoryException:`

try
{
    await repository.AddAsync(product);
    await unitOfWork.SaveChangesAsync();
}
catch (RepositoryException ex) when (ex.ErrorType == RepositoryErrorType.Add)
{
    // Handle or log rich error info
}
