I have my console in Dot Net Framework and I want to convert it into the Dot Net core , but while converting i faced some library related issues like whenever i am i used System related Library in dot net core it will give me error that this library is not suitable for dot net core . is there any library that i used alternative of system related library and there functions also so i can easily convert my application from dot net framework into dot net core.

i expect the alternatives of system related library to used in dot net core application , with the same functions present in the dot net framework related library.
