In September 2009 I posted the slides and code for the F# tutorial at JAOO 2009.
I've now updated this tutorial code for the F# Visual Studio 2010 Beta2 release (with matching CTP release for Visual Studio 2008). We've also added some more content and explanatory comments. For example, we've added the samples of LINQ queries using the F# Power Pack.
The updated ZIP and slides are on the original page
