Generic Repository Implementation

Repository Abstraction for Entity Framework

This generic Repository implementation for Entity Framework abstracts completely all EF-References from your business layer in a domain driven design manner.

Features

• Ready to use in seconds
• Abstracts all EF specific Code out of your business layer
• Easy to mock and test
• On .NET 9.0

How to use

• Add IEntity<T> interfaces to your domain classes
• Add IDataContext Interface to your DBContext class
• Use Extension RegisterRepositories() in your startup class or program.cs
• Inject IRepository<T> in your business layer
• Just use It

Step by step explanation

Add IEntity<T> interfaces to your domain classes:

public class Customer : IEntity<int>
{
 public int Id { get; set; }
}

Add IDataContext Interface to your DBContext class:

public partial class MyDbContext : DbContext, IDataContext
{ 
}

Use Extension RegisterDbContextAndRepositories() in your startup class or program.cs:

// Just register generic repositories and your dbContext which has the IDataContext marker interface
builder.Services.RegisterDbContextAndRepositories<MyDbContext>();

Inject IRepository<TEntity, TKey> (or IIntRepository, IStringRepository, IGuidRepository, ILongRepository) in your business layer:

public class MyService(IRepository<Customer, int> repository)
{ 
}

Just use it:

List<customer> customerWhoHavePayed = repository
 .Query(asNoTracking: true, asSplitQuery: true, includes: x => x.Invoices)
 .Where(x => x.Invoice.IsPayed)
 .ToList()
