Hey,

I know what you are saying, i.e. you could have a 2005 SLN file and a 2008 SLN file, both targetting the same projects, which didn't change as part of the upgrade. However, I was quite specific in the question that I asked him. I don't remember the exact reason that was given, but it was to do with the fact that it is a completely different CLR for .Net 4.0, where as before for .Net 3.0 and .Net 3.5, it was simply additions to the existing CLR.

Like you say, we will find out soon enough. It has been the 12th here for a whole 8 hours and 19 minutes, where is my download I don't like having to wait until they wake up
