Yep, definitely interested in the C#/VB and LINQ sessions and the F# session as well. The biggest frustration I've had with using F# together with C# and .NET projects and libraries is that the various "databinding/mapping/serialization/etc." systems in the various MS .NET frameworks (mapping in LINQ to SQL/EF, model binding in ASP.NET MVC, serialization in WCF, etc etc etc) all seem to assume mutable properties and default constructors. It would be great to either have ORM (RRM?)/services/whatever frameworks designed for F#, or a nice package of adapters etc. Of course I'm having to create some of the latter myself ...

oh and Silverlight for iPhone makes little sense, but Silverlight for Android makes a lot of sense. The time's about right to start talking SL5 too.
