کلاس DbContextTransactionAdapter همانطور که از نام آن مشخص می‌باشد، پیاده سازی از الگوی Adapter برای وفق دادن DbContextTransaction با واسط ITransaction، می‌باشد. متد BeginTransaction در صورتی که تراکنشی برای وهله جاری DbContext ایجاد نشده باشد، تراکنشی را ایجاد کرده و فیلد currentTransaction_ را نیز مقدار دهی می‌کند.

        {
            var transactionAttribute = GetTransactionaAttributeOrNull(methodInvocation.InstanceMethodInfo);

            if (transactionAttribute == null || _unitOfWork.HasTransaction) return methodInvocation.InvokeNext();

            using (var transaction = _unitOfWork.BeginTransaction(transactionAttribute.IsolationLevel))
            {
                var result = methodInvocation.InvokeNext();

                if (result.Successful)
                    transaction.Commit();
                else
                {
                    transaction.Rollback();
                }

                    methodInfo
                ).FirstOrDefault();

            return transactionalAttribute;
        }
    }

واسط ISyncInterceptionBehavior، مربوط می‌شود به کتابخانه جانبی دیگری که برای AOP توسط تیم StructureMap به نام StructureMap.DynamicInterception ارائه شده‌است. در متد Intercept، ابتدا چک می‌شود که که آیا این متد با TransactionAttribute تزئین شده و طی درخواست جاری برای Context جاری تراکنشی ایجاد نشده باشد؛ سپس تراکنش جدیدی ایجاد شده و بدنه اصلی متد اجرا می‌شود و نهایتا در صورت موفقیت آمیز بودن عملیات، تراکنش مورد نظر Commit می‌شود.
