SQL Server 2008 Developer Edition Install fail due to .NET Framework 3.5 missing
For a couple of seconds, I was in a state of surprise, as I had Visual Studio 2008 and it worked absolutely fine; without .NET Framework 3.5 VS 2008 should have not worked. I had a hard time wrapping my head around this idea. I searched online for the solution and successfully found the following link, which clearly gave explanation to my probing mind. As CSS SQL Server Engineers have already explained it perfectly I will be not talking about the same again, but I recommend this as a good read.
If you have installed VS 2008, install VS 2008 SP1 as well.
