When I go to the Role Manager, I do not see the .NET 3.5 SP1 listed. Here's a screenshot:

How do I check in SP1 is installed? I checked Application Server and installed the .NET 3.5.1 but some features that are available in SP1 are not enabled in my application – user25164 Mar 5 '10 at 13:35
3.5.1 is 3.5 SP1 - at least that's how I've always read that version string ;) Also see this question on SO: – Oskar Duveborn Mar 5 '10 at 13:51

You can install this directly without choosing application server under roles by going directly to "Features". There you choose to specifically install the .NET Framework with or without the WCF Activation piece.
