I have this simple class
C#namespace CodeRushIssue
{
class Program
{
static void Main(string[] args)
{
}
private static void Foo() { }
}
}
Move to inside the Foo() parentheses
Ctrl + .
Add Parameter
Type a type name (I used string)
Press Enter to move to the parameter name
Type whatever
Press enter to finish
At this point the parameters should have been added twice.
