Consider the following scenario:
- The Workspace Control Shell is used on Microsoft Windows Server 2012 R2 or later.
- This is configured in the Workspace Control Console in Composition > Desktop > Shell > Use Workspace Control shell as the default shell is selected.
- An application is started in the user session, but its window does not have the focus. This application uses TOAST messages to show notifications in the session.
- A new notification from that application is received.
In this scenario the applications TOAST message is not displayed.
The TOAST messages are not generated by applications, but by the Windows Notification System from the operating system itself.
This function is part of the Microsoft Windows Explorer Shell, which is not running when using the Workspace Control Shell.
Therefore these messages cannot be displayed.
Using the Microsoft Windows Shell for a Workspace Control session will display the Microsoft TOAST messages.
