1. Install nuget package

   Install-Package KirkChen.EFRepository 
   

2. Create data class with interface IEntity

   public class MyData : IEntity<int>
   {        
       [Key]
       public int Id { get; set; }
       
       public string Content { get; set; }
   }

3. Create dbContext

   public class MyDbContext: DbContext
   {
       public DbSet<MyData> MyDatas { get; set; }
   }

4. Create repository for data class

   public class MyDataRepository : GenericRepository<int, MyData>, IRepository<int, MyData>
   {
       public MyDataRepository(MyDbContext context)
           : base(context)
       {
           // Enable soft delete
           this.RegisterPostLoadHook(new SoftDeletePostLoadHook<MyData>());
           this.RegisterPostActionHook(new SoftDeletePostActionHook<MyData>());
       }
   }

5. Use reository

   var dbContext = new MyDbContext();
   var repository = new MyDataRepository(dbContext);
   var myData = repository.Get(1);

Using unit of work to handle transaction

using(var dbContext = new MyDbContext())
using(var unitOfWork = new UnitOfWork(dbContext))
{
    var repository = new MyDataRepository(dbContext);
    repository.Add(data);

    var anotherRepository = new OtherDataRepository(dbContext);
    repository.Add(anotherdata);

    unitOfWork.SaveChanges();
}
