Is .NET Framework v3.5 an upgrade to v3 or a separate product?

Basically, SharePoint says it needs .NET Framework 3 but when you search on that version on www.microsoft.com, it guides you towards v3.5

Cheers, Rob.

.net

  1. It is an extension to .NET 2 and .NET 3. You can not have 3.5 without also having 3 and 2. Install 3.5 and any updates and sharepoint will be happy.
    .NET 3.5 family update is available on microsoft update and is .NET 3.5 (which includes service pack 1 version of .net 3 and 2) and some updates on top of that to fix compatability problems introduced by the service packs.

  2. 3.5 is both a separate product and an upgrade - if that makes sense.

    The same install will either upgrade an existing installation or do a full install if there's no version already installed.

    It is a separate version.

    But it includes .NET Framework 3.0 SP1 and 2.0 SP1, for backwards compatibility.

  4. As far as IIS is concerned, ASP.NET 2.0 3.0 or 3.5 use the same version of the CLI so they are undistingable
