This book is a good light easy to carry overview but really short on some very significant details (com interop in particular) and has too much on useless topics like how to draw a circle on a form. It works as a readable introduction to vb.net but comes up short as a reference. After reading it I found myself constantly failing to find the information I needed.
Great new additions to vb.net such as regular expressions are largely ignored and the coverage of the .NET framework is very thin.
If you are an experienced vb developer you really should look for a book with more information on how to leverage your existing knowledge. Look for information on com interop and porting.
