You have no idea how much I dislike it when a .NET Framework assembly is called an "assambleya" in Russian. It is an ugly calque from English that has nothing to do with the word’s actual meaning in Russian.
In fact, the word assembly in this sense is translated as: СБОРКА.
A bunch of dictionaries from Yandex:
https://slovari.yandex.ru/search.xml?text=%D0%B0%D1%81%D1%81%D0%B0%D0%BC%D0%B1%D0%BB%D0%B5%D1%8F

Gramota.Ru:

Point out which one of them gives a definition of the word "assambleya" that even remotely resembles the intended meaning.
P.S. Using the English word "assembly" directly is not the best option either, but it is tolerable.
