Crazy. I've opened a bug:

Subject: [Ironruby-core] problem with WPF animation.Duration= and TimeSpan

Hi all,

Once again I am hitting some unexpected behavior in IronRuby. Might be a bug ;)
>>> animation = System::Windows::Media::Animation::DoubleAnimation.new()
=> #<System::Windows::Media::Animation::DoubleAnimation:0x000005c>

>>> animation.Duration= System::Windows::Duration.new( System::TimeSpan.FromSeconds(2))
=> #<System::Windows::Duration:0x000005e>

>>> animation.Duration= System::Windows::Duration.Forever
=> #<System::Windows::Duration:0x0000060>

So far everything works as expected. Now trying to directly set a timespan which should be possible in C#:
>>> animation.Duration= System::TimeSpan.FromSeconds(2)
:0: can't convert System::TimeSpan into System::Windows::Duration (TypeError)


ok, automatic conversion seems not yet to work here ... but the next thing is really strange:

>>> animation.Duration= System::Windows::Duration.new( System::TimeSpan.FromSeconds(2))
:0: can't convert System::TimeSpan into System::Windows::Duration (TypeError)

>>> animation.Duration= System::Windows::Duration.Forever
:0: can't convert System::TimeSpan into System::Windows::Duration (TypeError)

>>> ???

What has already worked now doesn't any more, depending on the value that has been set before. You will probably know what is going on.

Cheers,
