C# in comparison to C++: what is your strongest pain?

short a = 5;
short b = 3;
short c = a - b;

short c = (short)(a - b);

#define IF(test){bool _test; if (IfUtil(Protect(_test=(test))){
#define ELIF(test) } if (IfUtil(Protect(!_test && (_test=(test))))){
#define ELSE } if (IfUtil(!_test)) {
#define ENDIF }}

//
IF(some_test)
  ....
ELIF(another_test)
  ....
....
 ELSE
  ....
 ENDIF
