• تمیزکاری کد و خلوت شدن فضای کد‌نویسی
• ممکن هست بعدها گیج کننده شود که من چرا از این‌ها استفاده کردم؟ در آینده با نگاه به یک کد تمیزتر متوجه میشوید یک کد از چه چیزهایی برای انجام کارش بهره‌مند شده و هم اینکه در کارهای گروهی و تیمی هم این مورد به شدت تاثیرگذار هست.
• باعث کند شدن تحلیل‌های ایستا میشه (اینجا و اینجا )
• کمپایل شدن کد کندتر میشه
• موقع تست برنامه، اجرای اولیه کندتر خواهد بود چون CLR باید این نوع موارد را شناسایی و حذف کند
