Bill posted about Universal object references. I have no clue why
inline method invocation doesn't work for you in some cases - I am
unaware of any restrictions.

Web services do not require the adoption of .NET. SOAP is not .NET
only. Components and services (these will become one in the same) are
made consistent via OO - this is a good thing and is the best part of
OO - IMHO.

I've worked on large complex systems written in a variety of
languages. I've never seen a procedural code based system collapse
under it's own weight - I have seen SEVERAL OO systems implode.
