Leading underscores are written to immediately identify a variable as being private to that class (vs. a local).

I really think MS choose _ because they intentionally didn't want to use m.

But I can see the good in a universal standard, no thinking, no achievement, no responsibility, and no accountability.

private string aStr = "1234";
private int someInt = 1234;

int y1 = (int) aStr;
// Cannot convert type 'string' to 'int'

string z1 = (string) someInt;
// Cannot convert type 'int' to 'string'

int y2 =  aStr as int; 
// The as operator must be used with a reference type or nullable type ('int' is a non-nullable value type)

string z2 = someInt as string; 
// Cannot convert type 'int' to 'string' via a reference conversion, boxing conversion, unboxing conversion,
// wrapping conversion, or null type conversion
