Visual Basic.NET color syntax highlighting in Vim

I wish I had added these lines to my vimrc months ago. I’m not sure why they aren’t in vim’s filetypes.vim. My vim is pretty new. Perhaps I should file a feature request?

I’m really just using vim as a reader. Color syntax highlighting is nice in a source reader. Of course I wouldn’t have to read that way if work had source control and viewcvs. I think right now we are scoring between a 0-1 on the Joel test. I’d like to get us to 4 or 6 by my 1 year anniversary.
