As part of the upcoming (currently insider) version of the OneDrive client, the On-Demand feature of Microsoft has introduced some new shell / namespace extensions.
In the status column there is an additional column showing the status of file availability, as well as text.
Has Microsoft developed a special implementation of IShellView for synchronized OneDrive folders or some other shell interface? How did they connect to file selection change events?
I know that support for column handler extensions has been removed from a previous version of Windows.
Please provide me with some useful resources regarding the development of such functionality: custom columns and status bar extensions (preferably using C # ..).
