An updated version of GhostDoc 4 Beta 2 is available at http://submain.com/download/ghostdoc/beta/
A license key key good to 1/Sept/2012 is available at http://submain.com/blog/GhostDocV4Beta2IsAvailable.aspx
Ghost Doc is an excellent tool that I recommend to all VB.NET and C# developers. It will work with Visual Studio version 2005, 2008 2010 and 2012.
The comment template introduced with Version 4 is an excellent idea and needs only a minor adjustment via the options dialog to to get first time stylecop compliance. SubMain are to be commended for an excellent tool that just keeps getting better.
