Q: Re: IE support, I'd rather use C# for scripting than JavaScript. Absolutely!

A: We are working on Longhorn-timeframe work that will address this. You’ll be able to use markup and C# to do rich client apps in a web-like manner.

Q: Is it planned to have nulls for ValueTypes ?

A: We will most likely have an Optional generic type that can be used to combine a value type with a bool flag that says whether the value is present. You could then have ?Optional x;? and say ?if (x.Defined) DoSomething(x.Value);?.
