If you buy only one book, get "Programming Microsoft Visual BASIC .NET". It's part of the Core Reference, and written by Francesco Balena. It is a massive book, and covers almost all topics. It is very well written ean easy to understand, with great examples. This was one of the first .net books I picked up, and it is still the book I turn to the most when I need to look something up.
