Woo hoo. We launched http://MSSharePointDeveloper.com this week to coincide with TechEd Developers in Orlando, Florida. There's lots of material for .NET developers who want to see what building applications on SharePoint is like up there.
Please send me any feedback as comment on my blog about the MSSharePointDeveloper site. I would be pleased to hear what people think about it and any feedback or corrections you can think of.
The new content is all on Visual Studio 2005. It will all be the same on Visual Studio 2008 since the Visual Studio extensions for SharePoint are the same on both versions of Visual Studio.
Visual Studio 2008 extensions for SharePoint has just released today, so you can get that to do the hands on labs if you want also.
