The nestable object literal syntax obsoletes some cases where constructutors
were used before, and where named arguments would be used, but clearly not
all (deterministic initialization) - it can be used to initialize properties
via new Person() { First = "Bob", Last = "Smith" }; I can't remember the
exact syntax.

Thanks to Reddit I have found a nice short document that lists some of the
differences of C#4:
https://docs.google.com/View?docid=dcj4xk6_17ffc7nmgv
They have added a dynamic invocation, useful if you want to implement a
dynamic language (like IronPython, IronRuby, etc) on top of the dotnet.
Object-C shows this is doable in a very C-like language, and the Boo
language shows that in a statically typed language it can be useful to use
a Duck type once in a while to reduce the "static type pressure". More
info on this last concept in the Boo site.
Something that I like a lot is the named arguments, that I hope to see in
D and Delight someday. They are used often in Python, and they help
increase the readability of the code, sometimes even reducing mistakes.
They have used colons:
foo(x: 1, z: 3)
While Python uses equal signs:
foo(x=1, z=3)
I think they are about equally readable.
(I think there's a problem with named arguments, that you can solve in
some ways, for example with an extra hidden bitfield argument that encodes
what arguments are given and what not).
