Oh, I forget to tell everyone that I was on episode #73 of .NET Rocks!
Check it out here.
By the way, I said in the show that Whidbey Click Once uses the BITS (code name “drizzle”) technology that has been in Windows for many years now. However, someone at Microsoft informed me that I was incorrect. In Whidbey, Click Once does not use BITS. However, in Orcas/Longhorn, Click Once will use BITS.
