What .net Features are *not* available on Windows 2008 R2 Server Core?

So Windows Server Core 2008 R2 added support for ASP.net, but only a subset:

• Subset of .NET Framework 2.0
• Subset of .NET Framework 3.0 and 3.5 – WCF, WF, and LINQ

Now the question is, what is not available? I'm guessing that the Media stuff and everything related to WPF is missing, which isn't a huge loss. But any other big components that could hurt?

Edit: So far, found:

• WPF (Thanks Nick!)
• System.Web.Mail (depreciated in favor of System.Net.Mail anyway)

Only WPF support is not included, which makes sense, given it's graphical.
