That's one of the reasons I've pretty much given up on C# despite having 
initially been relatively impressed with it. They've had that giant, gaping, 
and frankly quite easy to remedy, lack-of-IArithmetic hole since C# first 
got generics (ie, forever ago), and there's been no shortage of people 
complaining about it. And yet, last I checked (numerous versions and years 
after the hole was created in the first place), MS still had yet to even 
acknowledge the issue, much less remedy it. Not the best management 
situation.
