.NET 3.0 and 3.5 in Windows Server 2008 R2 Server Core

.NET 3.0 and 3.5 in Windows Server 2008 R2 Server Core

Much like .NET 2.0 in Server Core, .NET 3.0 and 3.5 are also subsets of functionality. Included are:

·         Windows Communication Framework (WCF)

·         Windows Workflow Framework (WF)

·         LINQ

The only functionality not included is the Windows Presentation Framework (WPF).

.NET 3.0 and 3.5 functionality is installed with a single package:

·         Start /w ocsetup NetFx3-ServerCore

If 32bit support is needed you first need to install WoW64 and then .NET 2.0 WoW64 support, the following assume the above command has already been run:

·         Start /w ocsetup ServerCore-WOW64

·         Start /w ocsetup NetFx3-ServerCore-WOW64


  • Now that .NET is available in R2, does that mean ServerManagerCmd.exe will also be available?

    Or, if it's not, is Routing & Remote Access Services a supported role on R2?  The inability to set up site-to-site VPNs between Server Core machines is extremely frustrating.

    It appears that a reboot is required after the "start /w ocsetup ServerCore-WOW64" command. There was no prompt in the console indicating this was required and the c:\windows\logs\cbs\cbs.log was 0 bytes in size. I ran the command multiple times to no avail. "oclist | findstr /i wow" showed NOT installed. But during shutdown portion of the reboot I could see some updates were done (as per status messages) and after reboot cbs.log was a little over 1MB and oclist showed WOW64 support as installed.

    Perhaps consider updating the blog entry so that others that dont read the comments dont waste time.


  • こんにちは。(やはり、ブログに書いておくことにしました . . .) ご存じの通り Server Core は、Windows Server 2008 R2 で .NET 開発者にとっても無関係なものではなくなりました。いままでは

  • Hi, I can't even see the feature name on oclist output Dism not available and the comman to install it returns an error
    is there a workaround to install .net 3.0? thanks for the reply
