The biggest problem is that your projects must live in the “C:\Program Files\Samsung\Samsung TV SDK(3.1.1)\apps” folder. After a brief moment of outrage at not being able to store my code where I want, I found this blog post by Peter Friese which reminded me that Windows does actually support symlinks via the mklink tool – so running up
command as the local Administrator, going to the Samsung SDK folder, deleting the
apps folder (after first moving my code where I wanted it to be!) and typing
mklink /D apps c:\code\samsung_tv_apps
has fixed my problem!
