There are known problems with masks+registration in ManagedITK. I
don't have the time to track down or fix the issue(s). Sorry.

The ManagedITK home page says that ITK 4 *will* provide C# wrappers --
these have not yet been implemented. SimpleITK will support C#
wrappers very shortly (I have just sent a changeset). I'm not sure on
the timeline for WrapITK. I have updated the ManagedITK Google Code
page with this information.
