Unfortunately I've tried that already, and it appears not to exist:

 >>> import clr
 >>> clr.AddReference('ZedGraph')
 >>> from ZedGraph import XDate
 >>> d = XDate(1995, 1, 1)
 >>> XDate.op_Implicit(d)
Traceback (most recent call last):
AttributeError: type object 'XDate' has no attribute 'op_Implicit'
 >>> XDate.op_Implicit
Traceback (most recent call last):
AttributeError: type object 'XDate' has no attribute 'op_Implicit'
