Nice work - ive been working around this to figure out what dependencies are missing that VS mitigates.(trying to get UE publishing working without VS installed- seems a bit of a sledgehammer approach)
I have been able to get android/Quest deployment working on 5.03 by just installing Android studio 4.0 & the .Net runtimes (windowsdesktop-runtime-3.1.29-win-x86)
Similarly, publishing to windows is opened up by just installing the windows app SDK - (Windows SDK - Windows app development | Microsoft Developer)
BUT - there remains an issue if a project contains a plugin, so the VR template for example will not package - has anyone figured a workaround for this? (by which i mean a more targeted workaround than the current fix of installing Visual Studio!)
