You can use the Deployment Image Servicing and Management (DISM) command-line tool to create a modified image to deploy .NET Framework 3.5.

Important

For images that will support more than one language, you must add .NET Framework 3.5 binaries before adding any language packs. This order ensures that .NET Framework 3.5 language resources are installed correctly in the reference image and available to users and applications.

Using DISM with Internet connectivity

Requirements

• Internet connection

• Access to Windows Update. If the PC or server is behind a firewall or uses a proxy server, see KB900935 - How the Windows Update client determines which proxy server to use to connect to the Windows Update Web site.

• Windows 8, Windows Server 2012, or the Windows Assessment and Deployment Kit (ADK) tools.

• Installation media

• Administrator user rights. The current user must be a member of the local Administrators group to add or remove Windows features.

For an online reference image that can access Windows Update

1. Open a command prompt with administrator user rights (Run as Administrator) in Windows 8 or Windows Server 2012.

2. To Install .NET Framework 3.5 feature files from Windows Update, use the following command:

   Use /All to enable all parent features of the specified feature. For more information on DISM arguments, see Enable or Disable Windows Features Using DISM.

3. On Windows 8 PCs, after installation .NET Framework 3.5 is displayed as enabled in Turn Windows features on or off in Control Panel. For Windows Server 2012 systems, feature installation state can be viewed in Server Manager.

For an offline reference image

1. Run the following DISM command (image mounted to the c:testoffline folder and the installation media in the D:drive) to install .NET 3.5:

   Use /All to enable all parent features of the specified feature.

   Use /LimitAccess to prevent DISM from contacting Windows Update/WSUS.

   Use /Source to specify the location of the files that are needed to restore the feature.

   To use DISM from an installation of the Windows ADK, locate the Windows ADK servicing folder and navigate to this directory. By default, DISM is installed at C:Program Files (x86)Windows Kits8.0Assessment and Deployment KitDeployment Tools. You can install DISM and other deployment and imaging tools, such as Windows System Image Manager (Windows SIM), on another supported operating system from the Windows ADK. For information about DISM-supported platforms, see DISM Supported Platforms.

2. Run the following command to look up the status of .NET Framework 3.5 (offline image mounted to c:testoffline):

   A status of Enable Pending indicates that the image must be brought online to complete the installation.

Using DISM with no Internet connectivity

You can use DISM to add .NET Framework 3.5 and provide access to the sourcesSxS folder on the installation media to an installation of Windows that is not connected to the Internet.

Warning

If you're not relying on Windows Update as the source for installing the .NET Framework 3.5, make sure to use sources from the same corresponding Windows operating system version. Using a source path that doesn't correspond to the same version of Windows won't prevent a mismatched version of .NET Framework 3.5 from being installed. This can cause the system to be in an unsupported and unserviceable state.

Requirements

• Windows 8, Windows Server 2012, or the Windows ADK tools.

• Installation media

• Administrator user rights. The current user must be a member of the local Administrators group to add or remove Windows features.

Steps

1. Open a command prompt with administrator user rights (Run as Administrator).

2. To install .NET Framework 3.5 from installation media located on the D: drive, use the following command:

   Use /All to enable all parent features of the specified feature.

   Use /LimitAccess to prevent DISM from contacting Windows Update/WSUS.

   Use /Source to specify the location of the files that are needed to restore the feature.

   For more information on DISM arguments, see Enable or Disable Windows Features Using DISM.

On Windows 8 PCs, after installation, .NET Framework 3.5 is displayed as enabled in Turn Windows features on or off in Control Panel.

.NET 3.5 cant be install by internet. you have to use your installation DVD or ISO downloaded from Microsoft website. use this command to install

DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:d:sourcessxs /All /LimitAccess

d: should be the

• ISO mapped drive if you use ISO file
• DVD drive if you use installation DVD

Few important points.

• If you use ISO file, There can be errors if you try to use a ISO from a network location.
• If you download ISO from Microsoft web site careful about 32 bit and 64 bit.
• Run command prompt as Administrator to run this command
• If your command prompt hang without any response, probably it means Some windows updates installation is in progress. So restart the computer and try again.
• Go to 'Turn Windows feature on or off' window.If you installed properly, you can see .NET framework 3.5 is installed.

Here is the step by step guide I have written. http://codeketchup.blogspot.sg/2015/11/how-to-install-net-framework-35-on.html

If you have access to MSDN subscription, download the Windows 10 Features on Demand ISO, mount it and run this command:

(where D: is the mounted ISO)

If this fails, run this command to add the files back to your Windows

and now go to the UI to enable the feature.

If you don't have your Windows installation media at hand or want it easier:

These are the methods without the commandline DISM command, which work interactively- for the first two you need current internet access:

1. Normally it is enough to start an application requiring .NET 3.5 and Windows will bring up a dialog for installation over internet.

2. Type 'windows feature' in the magnifier (search) line besides the start button and switch to

   Turn Windows features on or off
   Control panel

   Then you find the known dialog from previous versions to turn .NET 3.5 features on, etc. (At least I was unable to find it from new settings dialog without search.)

3. If you updated Windows 10, and you had .NET 3.5 activated before on Win 7 or 8.x, then you have to do nothing, it is also activated in Windows 10.

4. Here is the real offline 'emergency' installer:http://www.smart-arab.com/2013/12/install-net-on-windows-8-1-and-windows-10-offline/Of course this is not the official way.

You need to go to add remove programs and then add features to windows, then select it from here. This will install .net 3.5 and 2.0

edit 1

Please open a command prompt (cmd.exe) as admin and run the following command to install .Net 3.5:

(replace D: with your mounted Win10 ISO)

In some environment, DISM fails to fetch the file (Proxy, network policies). The DISM command takes the files from the DVD and you're fine

1. Open CMD as an administrate

Command: Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:sourcessxs /LimitAccess

here D=partition name Mout

Open ISO file of windows 10 and type D where Partition.

Finally Open Windows Features and then you will see Net Framework 3.5 has been install and enable.
