Mailbag: What version of the .NET Framework is included in what version of the OS?

  • [アーティクル]

Question:

I recently installed Windows Vista.  When I looked in the Programs and Features (formerly known as Add/Remove Programs) control panel, I didn't see the .NET Framework 2.0 listed.  Therefore I decided to install the .NET Framework 2.0 by downloading it from this location.  However, running that setup displays an error message stating that it cannot be installed because it is already a part of the OS.  Why does this happen?

Answer:

Over the past few months, I've received several variations on this question for other operating systems and all of the released versions of the .NET Framework.  When the .NET Framework is installed as a part of the OS, it does not appear in the Programs and Features (or Add/Remove Programs) control panel.  The following is a complete list of which version of the .NET Framework is included in which version of the OS:

  • Windows XP Media Center Edition (Windows XP SP1) includes the .NET Framework 1.0 + SP2 as an OS component
  • Windows XP Media Center Edition (Windows XP SP2 and higher) includes the .NET Framework 1.0 + SP3 as an OS component.  On Windows XP Media Center Edition, the only way to get the .NET Framework 1.0 SP3 is to install Windows XP SP2 or higher.  There is not a standalone 1.0 SP3 installer for this edition of Windows XP.
  • Windows XP Tablet PC Edition (Windows XP SP1) includes the .NET Framework 1.0 + SP2 as an OS component
  • Windows XP Tablet PC Edition (Windows XP SP2 and higher) includes the .NET Framework 1.0 + SP3 as an OS component.  On Windows XP Tablet PC Edition, the only way to get the .NET Framework 1.0 SP3 is to install Windows XP SP2 or higher.  There is not a standalone 1.0 SP3 installer for this edition of Windows XP.
  • Windows Server 2003  (all x86 editions)  includes the .NET Framework 1.1 as an OS component; 64-bit versions of Windows Server 2003 do not include a version of the .NET Framework as an OS component
  • Windows Vista (all editions) includes the .NET Framework 2.0 and 3.0 as OS components  3.0 can be added or removed via the Programs and Fatures control panel.
  • Windows Vista SP1 (all editions) includes the .NET Framework 2.0 SP1 and 3.0 SP1 as OS components.  3.0 SP1 can be added or removed via the Programs and Features control panel.
  • Windows Server 2008 and Windows Server 2008 SP1 (all editions) includes the .NET Framework 2.0 SP1 and 3.0 SP1 as OS components.  The .NET Framework 3.0 SP1 is not installed by default and must be added via the Programs and Features control panel though.
  • Windows Server 2008 SP2 (all editions) includes the .NET Framework 2.0 SP2 and 3.0 SP2 as OS components.  The .NET Framework 3.0 SP2 is not installed by default and must be added via the Programs and Features control panel though.
  • Windows Server 2008 R2  (all editions) includes the .NET Framework 3.5.1 as an OS component.  This means you will get the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes.  3.0 SP2 and 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 7 (all editions) includes the .NET Framework 3.5.1 as an OS component.  This means you will get the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes.  3.0 SP2 and 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 8 (all editions) includes the .NET Framework 4.5 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 8.1 (all editions) includes the .NET Framework 4.5.1 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows Server 2012 (all editions) includes the .NET Framework 4.5 as an OS component, and it is installed by default except in the Server Core configuration.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Server Manager.
  • Windows Server 2012 R2 (all editions) includes the .NET Framework 4.5.1 as an OS component, and it is installed by default except in the Server Core configuration.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Server Manager.
  • Windows 10 (all editions) includes the .NET Framework 4.6 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 10 November 2015 Update (all editions) includes the .NET Framework 4.6.1 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 10 Anniversary Update (all editions) includes the .NET Framework 4.6.2 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows Server 2016 (all editions) includes the .NET Framework 4.6.2 as an OS component, and it is installed by default except in the Server Core configuration.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Server Manager.
  • Windows 10 Creators Update (all editions)  includes the .NET Framework 4.7 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 10 Fall 2017 Creators Update (all editions)  includes the .NET Framework 4.7.1 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 10 April 2018 Update (all editions)  includes the .NET Framework 4.7.2 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.
  • Windows 10 May 2019 Update (all editions)  includes the .NET Framework 4.8 as an OS component, and it is installed by default.  It also includes the .NET Framework 3.5 SP1 as an OS component that is not installed by default.  The .NET Framework 3.5 SP1 can be added or removed via the Programs and Features control panel.

Note - for the .NET Framework 2.0, 3.0 and 3.5, you can see a graphical view of the above information in this blog post.

In addition, the .NET Framework shipped with the following versions of Windows but not as truly integrated OS components:

  • Windows XP Home and Professional SP1 includes the MSI-based .NET Framework 1.0 + SP2 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows XP Home and Professional SP2 includes the MSI-based .NET Framework 1.1 + SP1 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows XP Home and Professional SP3 includes the MSI-based .NET Framework 1.1 + SP1 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows Server 2003 R2 includes the MSI-based .NET Framework 2.0.  It appears in Add/Remove Windows Components as an OS component, but selecting it simply invokes the MSI-based installer.  The MSI can be repaired and removed using Add/Remove Programs regardless of whether it is installed via the standalone MSI or via the Add/Remove Windows Components UI.

You can see a table of what version numbers are associated with each version of the .NET Framework in this blog post.

    Hi Someone - The only version of the .NET Framework that ships as a part of the OS on any version of Windows XP Tablet PC or Media Center Editions is 1.0.  There may also be other pre-installed versions of the .NET Framework that come with a new computer that has one of these OS's pre-installed, but those other versions will be installed using the MSI-based setup and will appear in Add/Remove Programs.

    Hi Franklesniak - Thanks for the feedback - I'll update the table in this blog post with this information.My understanding is that the only way to get the .NET Framework 1.0 SP3 for Windows XP Tablet PC Edition or Windows XP Media Center Edition is to install XP SP2 or XP SP3.  I don't know of a standalone installer for the .NET Framework 1.0 SP3 on those versions of Windows XP.

    Aron,Is it possible to install VS 2008 (90 day trial) on windows 7 ?I un installed .Net 4  and verified 3.5 and 3.5 sp1 successfully .I tried installing VS 2008 in both Win 7 enterprise and home premium edition .In both the o/s I got the same error missing NetFX2.0-KB936704-v6000-x86_RTM_en.msu file from bootstrapper directory.I do have SQL 2008 installed on my Win 7 enterprise machine. But it shouldn't really matter.Is there clean step by step approachMy friends were able to install VS 2008 on Win XP Pro without any problem.Basically I need asp_net compiler to build a web site and make dll and make file, Do you have any other route?Ray

    Hi Ray Go - Yes, it should be possible to install VS 2008 on Windows 7 - I have it installed on my Windows 7 computer currently.The error you are getting sounds like it might be due to a corrupt download of the setup package that you're installing from.  I'd suggest trying to re-download and re-run VS 2008 setup to see if that helps resolve this error.

    Hi Aaron,Could you please help me with my issue. I had an application which was developed in .Net framework 2.0 and was working fine with windows XP...Recently when I installed Win7, my application has stopped working..Could it be some sort of compatibility issue??

  • Anonymous
    November 17, 2013
    Hi Sharon - Yes, it is possible that you're running into a compatibility issue.  Windows 7 includes the .NET Framework 3.5.1 as a part of the OS, and that includes the .NET Framework 2.0 SP2 and 3.0 SP2 behind the scenes.  When you've been using your application on Windows XP, did you have the original release of the .NET Framework 2.0 installed, or did you have the .NET Framework 2.0 SP2 installed?What kind of error do you see when you try to run on Windows 7?  Are you able to debug it to try to narrow it down further?

    Hi Aaron,I am new to this application, so I am not aware that whether we had the original release of the .NET Framework 2.0 installed, or the .NET Framework 2.0 SP2 installed!!Actually I don't see any error, but it stops working...When I open the application, it starts up, but when I open any task inside it, it closes by itself, without giving any error.

    Hi Sharon - In your original comment, I was under the impression that you were the developer of the application.  It sounds like you're a user of the application, not the developer.  In that case, I'd suggest contacting the application's manufacturer to see if they have any known issues on Windows 7 and/or have any patches or new versions available to download.When the application starts up and closes by itself, you can usually go to the Application Event Log (by running eventvwr) and looking for warnings and errors to get more details about the cause of the crash.

    Just to clarify my statement above: "it's 4.5 the one which comes with the DVD";I based this statement on what the "Add roles and features Wizard" reports.If that wizard is incorrect, then I don't know.It seems like Microsoft did not provide a easy way to find the .net version from powershell cmdlet, so I can't double check.if anyone knows a easy way to double check, please share.Domenico.

    Hi Domenico - My understanding was that Windows Server 2012 R2 came with the .NET Framework 4.5.1, not 4.5.  However, I don't have that version of Windows installed to confirm that statement at this time.  If you have the time, could you please try to use the sample code listed at blogs.msdn.com/.../9763379.aspx to see what it reports on your WS12 R2 system?

    sorry,I don't have time to learn WIX and compile a program in order to do what Microsoft did not do (provide a built in program to check net framework version).

  • Anonymous
    February 02, 2015
    Hi Domenico - The link I posted previously is C++ sample code that is built into a small .exe.  It doesn't require doing anything with WiX.  If you don't have time to compile and run that .exe, you could alternatively download and run the .NET Framework setup verification tool from blogs.msdn.com/.../8999004.aspx.  It creates a log file in %temp% that lists the versions of the .NET Framework that it thinks are installed on a PC, and it uses code that is nearly identical to the sample code from my previous reply.

      Hi Jamie McGregor - The .NET Framework 4.6.1 is an in-place upgrade for all versions of the .NET Framework from version 4 through 4.6. You don't need to install the .NET Framework 4 or 4.5 after installing 4.6.1, and the installers for the .NET Framework 4 and 4.5 won't allow you to install if 4.6.1 is already present on your PC - they'll tell you that a newer version is already installed.
