I have been using VS2010 for a few months now, and recently started
using the RTM version due for public release shortly. Although C# 4.0 is
by and large unchanged, defaults and dynamics are two of the big ones
that I'm already trying to implement in all my C# code, they are
definitely handy additions.

Another big one is a redefinitionof IEnumerables to finally support co-
as well as contra-variance.

COM interop has been improved, I've not yet dabbled too deeply into
this, but Office Server 2007/2010 and Office 2007/2010 interop seems,
from what little I've played with them, fairly simple.

Has anyone out there tried .NET 4.0 in PowerShell 1 or 2 CTP? I'd be
interested to hear any experiences on this.

All in all, I'm enjoying the new .NET 4.0 and C# 4.0, I think most
programmers with experience in other languages, as you mentioned C++
will certainly find it a friendlier albeit slightly stricter version...
a good thing IMHO.

Kind regards,
