System.DateTime.Op_Addition

Hey,

On one of my computers, I am using the following function to add dates.
System.DateTime.Op_Addition

I am on my laptop and when I type in System.DateTime., the intellisense doesn't show that function at all.

Does anyone know why that is? Am I missing any files?
I have .NET Framework 1.1.4322 which is the same as on my desktop.

Thanks,
