LiveShare

Live Share enables you to quickly collaborate with other people on the same code without the need to sync code or to configure the same development tools, settings, or environment.

In the case of the ACS workshop it will be very useful to work in the project, hosting a LiveShare session from the ACS Virtual Machine and sharing it with each member of your group.
