سلام
من تو یک پروژه با زبان سی شارپ و بانک اطلاعاتی sql از تکنولوژی LINQ استفاده کردم. ولی موقع اجرای فرم خطای time out میده، ولی بعد از اعلام خطا وقتی دوباره F5 میزنم مشکل حل میشه و برنامه اجرا میشه.
مشکل از چیه و چه جوری میشه درستش کرد؟؟؟
:گریه: :عصبانی++::گریه:
متن توضیحات خطا رو اینجا گذاشتم شاید لازم بشه:
