Yet to try it out, but this has great potential to make my life a whole lot easier; going between VBScript and C# is not pleasant...if I forget one more then in a VBScript if statement, I may kill someone.
Anyway, found the link on Tim Sneath's blog, you can find the tool here.
It is still an alpha, so it won't be perfect!
UPDATE: Not perfect is an understatement - only converts to VB.NET; pretty useless in an all C# shop! Code it generates still requires significant work to work properly...hmm...
