Deploying update to MSIX application while the application is in use

Hi,

I did some testing with MSIX applications and SCCM (we discussed it in MSIX community: https://techcommunity.microsoft.com/t5/MSIX-Deployment/Updating-an-MSIX-application-via-SCCM/m-p/737754#M226)

Short story:

I deploy application A. I then deploy application B, which is higher version of the same software, packaged also as MSIX and using the same family name so both MSIX will understand they are related. I specify supersedence between them so also SCCM is aware of this relationship. If I deploy application B to the client where application A is in use, the update will not happen. It only works when application A is closed during installation of app B.

It would be great if it could be installed while the application is in use. This can be achieved with MSIX when deployed using the App Installer solution, so I thought SCCM could do this too.
