Docker on Windows use Hyper-v virtual machine to run Linux Container. But with the new version of Windows there is the WSL (Windows subsystem for Linux). The new version WSL2 currently in beta, is used by the Edge version of Docker to run Linux Container without the virtual machine. This feature is an optional settings from version 220.127.116.11.
But on my development machine, the Edge installer suffer of the same problem of the stable one. The installation seems to complete without problem, but Docker do not works. The problem is the same: wrong version o Syste.Net.http, the installer ends with no problem, the Docker service seems to start but it is in not working state. Also the Doker Desktop client do not start. To solve the problem the solution is the same of the linked article, edit the config file for the service and Docker Desktop. After that you can anjoy Docker on WSL 2.
