Brief description of your issue

When running "VS" and running a config file. If the config file requires to add a workload and it does not exist, the install will fail with 8006.
It would be better to say that the IDE is running. Close it and try again.

VSComponents🛡 [Workloads ManagedDesktop]

The configuration unit failed while attempting to apply the desired state.
Visual Studio Installer failed with error code 8006 using arguments: modify --productId Microsoft.VisualStudio.Product.Community --channelId VisualStudio.17.Release --quiet --norestart --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workl…

Some of the configuration was not applied successfully.

Steps to reproduce

Have VS community installed and some work loads. I chose managed desktop.
Run the IDE
Now run a config file that adds a new workload.

Rather than succeed it fails.

Expected behavior

Expect to tell the user to shut down the IDE.

Actual behavior

Gives error but no direction

Environment

PS C:\Users\kevinla\.nuget\packages> winget --info
    Windows Package Manager (Preview) v1.11.280-preview
    Copyright (c) Microsoft Corporation. All rights reserved.

Windows: Windows.Desktop v10.0.26410.1000
System Architecture: X64
Package: Microsoft.DesktopAppInstaller v1.26.280.0

Start by reproducing the issue with Visual Studio running and a configuration that adds a missing workload, using the VSComponents unit and the reported error 8006 as the entry point. Inspect how the unit reports the failed Visual Studio Installer operation; done when the failure clearly tells the user to close the IDE and retry.
