SCCM PFE Steve Rachui has written an excellent posting all about the SCCM 2012x Application Model and advanced detection logic.
Like many postings written by Steve, they contain TONS of worth while information, even though I’ve to read it a couple of times in order to ‘wrap my head around it’.
So whenever you’re into SCCM and interested into the deeper aspects of the application model THIS is the place to start. The same posting contains links to previous postings all about the application model as well.
Thanks Steve for sharing!
