I want to set the Masterpage for System pages (eg, /_layouts/15/Settings.aspx) on a SharePoint Foundation 2013 site to a masterpage that is different than the default masterpage being used by the normal site pages.
I have set the MasterpageUrl property on the SiteCollection but that has made this masterpage also apply to System pages.
This is a SharePoint Foundation 2013 site, so I do not have access to Publishing Features or other Server specific features. I do have access to PowerShell and/or creating custom solutions.
