        {
            ....
            ControllerBuilder.Current.SetControllerFactory(typeof(DecryptingControllerFactory));
        }

حال برای استفاده از Context تولید شده، به صورت زیر شیءایی را ساخته:

 static DbContext _dbContext=null;
        public static DbContext GetDbContextInstance()
        {
            if (_dbContext == null)
            {
                string path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
                var dllversionAssm = Assembly.LoadFile(path + "\\ProjectContext.dll");
                Type type = dllversionAssm.GetType("DbContextGenerator.TestContext");
                _dbContext = (DbContext)Activator.CreateInstance(type);
            }
            return _dbContext;
        }

و سپس برای ساخت DbSet از هر Entity به کد زیر نیاز خواهیم داشت:

public static System.Data.Entity.DbSet<T> Get<T>() where T : class
        {
            var set = GetDbContextInstance().Set<T>();
            return set;
        }

هم اکنون می‌توان رکوردهای Entity‌ها را واکشی کرده و یا آن‌ها را با یکدیگر Join بزنیم:

            var products = Get<Product>().ToList();

            var productTypes = Get<ProductType>().ToList();


            var query = from p in Get<Product>()
                        join pt in Get<ProductType>() on p.ProductTypeId equals pt.Id
                        select new
                        {
                            Id = p.Id,
                            Name = p.Name,
                            ProductType = pt.Name

                        };

            var JoinResult = query.ToList();

و نتیجه واکشی ها

و به شکل زیر پیاده سازی CheckArgumentIsNull را در ApplicationDbContext انجام دادم:

public interface IUnitOfWork : IDisposable
    {
        DbSet<TEntity> Set<TEntity>() where TEntity : class;

        int SaveChanges(bool acceptAllChangesOnSuccess);
        int SaveChanges();
        Task<int> SaveChangesAsync(bool acceptAllChangesOnSuccess, CancellationToken cancellationToken = new CancellationToken());
        Task<int> SaveChangesAsync(CancellationToken cancellationToken = new CancellationToken());
        void CheckArgumentIsNull(string v);
    }  
 

void CheckArgumentIsNull(string arg)
        {
            if (arg == null)
                throw new ArgumentNullException(nameof(arg));
        }

آیا کاری که کردم درست است؟

 int a = default(int);

var number = default(int); // 0
var date = default(DateTime); // DateTime.MinValue
var obj = default(object); // null

int a = default; // 0
Guid guid = default; // 00000000-0000-0000-0000-000000000000

if(s == default)
{

}
