Recently i came across a problem where someone had written a code with

int main(Array<String^>^ args){
    if (args->Length < 2){
        printf("enter more than 2 arguments");
    }
}

I want to know how this compares against

int main(int argc, char* argv[]){
    if (argc < 2){
        printf("enter more than 2 arguments");
    }
}

Why isn't the former code used a lot?
