Когда я нажимаю кнопку Button1 в первой форме -> появляется вторая форма. но когда я нажимаю кнопку 1 во второй форме, у меня возникает исключение FileNotFound. Что я делаю неправильно? Есть интересный момент. Этот пример с некоторыми изменениями работает в C # (/5365854/sborka-sborki-iz-drugoi-tolko-chto-skompilirovannoi-sborki) Может быть, есть люди, которые знают vb и c # и помогают мне понять различия между двумя примерами?

Вы пытались заменить assemblyDomain.DoCallBack(AddressOf assamblykub) простым вызовом функции assamblykub?
