زیبا سازی پروژه و بهترین Design ها

با سلام خدمت همه اساتید

در این تاپیک سعی بر اینه که به نحو خوبی سعی در استفاده بهینه از قابلیت های wpf بشه

چیزی که تا به الان دیدم مخصوصا در برنامه نویسی wpf در ایران اینه که هنوزم سعی میکنن به روش winform برنامه تهیه کنن

در wpf راه های بسیار زیادی وجود داره تا پروژه های بسیار شاخص و زیبا طراحی و اجرا کرد

به طور مثال و برای نخستین حرکت کنترل gift برای فایل های متحرک که در صورت استفاده نمای بهتری به برنامه میده
