In PB .net 12.5.2 how does one compile resources (ie bmp etc) into .exe/dll

I've got 2 WPF targets, both were recently migrated from PB 6.5 to PD 12.5 Classic, then to PB .net. It appears that for one of them the resource files are compiled into the exe (don't have to be deployed explicitly with the app), but not the other. The resource files are all listed as references in both apps. I don't see any differences in the project objects. There has to be a way to specify to compile the resource files into the exe/dlls, Doesn't there?

Thanks in advance,
