I jumped back into some compact framework development this weekend, and it was the first time since I had installed VS 2008 RTM. I went to connect to one of my CE devices via Visual Studio 2005, and was unable to connect. I also tried the remote performance monitor power toy.
I finally went to check on what version of the CoreCon files I had installed, and noticed right away that there date modified was 11/7/2007. I coped these latest versions over to my CE device, and was able to connect again.
