I was recently asked what the prerequsites was for deploying application to users as Available.
It turns out the customer was interested in moving from Application Catalog to the new Software Center which in turn made them ask some questions.
Previously in the Silverlight based Software Center users were unable to install applications that was Available to them. They had to open Application Catalog to see those applications.
It turns out that while you can install available applications through the new Software Center you still need Application Catalog installed and configured in ConfigMgr even though you don’t have to browse browse it and can effectively hide it for the user.
This is good to know since Microsoft mentions that Application Catalog is no longer supported after June 2018.
Edit: I got a response from Microsoft on Twitter saying that this should be fixed in 1806. Lets hope that it is!
