Microsoft is offering three VS 2008 PDF for free download but...

Just found the following in my email today from Microsoft - just click the following link:

http://go.microsoft.com/?linkid=9624136

After signing up, it allows you to download the three books (from Microsoft Press) in PDF format:

Programming Microsoft LINQ

Introducing Microsoft Silverlight 2

Programming ASP.NET 3.5

I was expecting the whole book but only selected chapters of each book is provided : (

However, Microsoft does provide some other pdf books for free such as:

Improving .NET Application Performance and Scalability (a bit old printed in 2004)

Composite Application Guidance for WPF (but requires simple registration - just log into hotmail)
