Win8 does not install the .Net 3.5 Framework directly on the Internet.

  

Every time you reinstall Windows 8 because of the development needs. The .Net3.5 Framework has to wait a long time to install successfully.. Later I found myself too stupid... Actually Can not be installed on the network... Let me introduce it.

1, first need to find the location of the installation file, my is in the D drive. (D: \\)

2, then right click on the bottom left corner of the start menu (Win + X) , select - command prompt (admin).

3, then enter the following command: dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\\sources\\sxs (Note: D:\\sources\\sxs is the location of the Win8 installation file)

4. Press Ctrl+U to go to the control panel to view

5. Restart!

In fact, the ISO8 file on Windows8 comes with the .net 3.5 Framework, but it must be updated online directly through the control panel. It may be because of the system mechanism that Windows has to connect to the Update online installation. If your internet speed is not strong, try this method.
