I use post build rules as part of my typical build process to create a common directory to reference everything from. Pointing build output to a common directory doesn't work because of bugs in Visual Studio.NET and file locking.

I seemed to remember someone having an add-in that added post build command lines to VB.NET and found it here: http://www.microsoft.com/downloads/details.aspx?FamilyId=3FF9C915-30E5-430E-95B3-621DCCD25150&displaylang=en
