Basically the shell looks for an active TCP stack. If it finds one it classes this as an active network. You can test by enabling and disabling your Network Connection in windows. It should work in real time and update the UI accordingly.
I have installed a licensed version on VS2013 but it seems to hang on my build. My lightswitch app hangs on loading.... when do not use this shell or theme, my build works fine. I checked the readme txt and it is version for vs2013. any thoughts
