Why do we enclose the `Main` function inside of a class in C#?

After learning C++, I think it makes sense to include the

main

main

function outside of a class. Why do we not do it in C#?
Like what disadvantage I would have by not including the

main

main

function in a class in C++? Would it be accessible to everyone? Does including the

Main

Main

method in a class in C# make it "safer" than it being present at a global scope? What is the reason behind this?
