Discussion is breaking out in the comments to this one.
  • Code Reuse is (Damn) Hard – James Michael Hare discusses Code Reuse, one of the commonly specified advantages of Object Oriented Programming’, looking at some principles which suggest reuse is possible, types of code which may be good candidates for re-use, and talks about how hard it can be to ensure reuse.

His follow on post answers a number of the criticisms of dynamic in C# received in response to the first article.
  • Anonymous Types are Internal, C# 4.0 Dynamic Beware! – ‘Ashic’ shows a potential confusion point with working with dynamic and anonymous types calling methods between assemblies as anonymous types are internal which results in runtime errors when calling across assembly boundaries.
