.NET Framework 3.5 SP1 Package Clarification
We’ve been noticing some questions regarding the recent update for Microsoft .NET Framework 3.5 titled “Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847)”. This update includes a full family update for .NET Framework bringing versions 2.0 and greater, up to version 3.5 SP1, as well as a small compatibility update for .NET Framework 3.5 SP1.
If you already have .NET Framework 2.0 or higher installed, you will be offered this update as an Important Update. If you do not have .NET Framework 2.0 or higher installed, then you will be offered a Recommended Update. For those users who already have .NET Framework 3.5 SP1 installed, only the app compatibility update will be installed as part of this update; for all other users, .NET Framework 3.5 SP1 will be installed, followed by the compatibility update.
Hope this helps,
