Install Net Framework 3 5 in Windows 10 Offline

An example is my video using Windows 10 version 1909 with iso sources that match the version too.

Please download the source :

If you have a different version of Windows, for example, version 1903 or below, this method might not work well, please first look for the iso sources file and place it in a folder with the application, or next I will share Source Iso for another version.
