[Question] How to get active projects (plural, when more than 1 is active)

[m-rray]

I see how to get the active project when one item in the solution explorer is selected, but looking through all the issues and samples here I can't see anything that details how to handle a situation where multiple projects are selected.

I have a group that inserts in the right click menu of project, projects or solution folders

public static CommandGroupConfiguration Group =>
            new CommandGroupConfiguration(
                GroupPlacement.VsctParent(new Guid("d309f791-903f-11d0-9efc-00a0c911004f"), 0x0402, 0x0600),
                GroupPlacement.VsctParent(new Guid("d309f791-903f-11d0-9efc-00a0c911004f"), 0x0418, 0x0600),
                GroupPlacement.VsctParent(new Guid("d309f791-903f-11d0-9efc-00a0c911004f"), 0x041C, 0x0600))
            {
                Children =
                [
                    GroupChild.Command<MyCommand>()
                ]
            };

When multiple projects are selected I can see in the client context
{[Shell.SelectedItemCount, 2]}
But i can't figure out how to then get which they are. Anything in the docs or samples around "ActiveProject" only seems to ever work with one.

Is this possible currently, without using the inproc sdk services?
