In the last couple of months I have made a number of presentations on new C# and Visual Basic language features in Visual Studio 2008 at seminars and conferences such as the following:

Dynamicwebs Partnerkonference 2008: The missing LINQ – en kort introduktion til LINQ

Aarhus .NET User Group: C# og VB sprognyheder i Visual Studio 2008

As well as a couple of Microsoft events...

If you are interested you can download a PDF with the slides (in Danish).
