The issue is that while the static methods on TimeSpan work, the instance
t = System::TimeSpan.from_seconds(1.1) # works
m = t.total_milliseconds # doesn't work
All my testing done on iron7 on WP7 of course!
The route of this problem seems to be (from Tomas Matousek):

We're thinking about this... one thing is that I think we could allow this
for Get methods - for readonly properties - I need to read the code a bit (a
