I tried to edit a project template after exporting it from vs2010 by extracting it and after editing compressing it again. But after that it won't show up in visual studios new project dialog.
So I tried it again, without the editing. Just extract and compress again. I even used windows zip mechanisms, but still wont work. Only the exported template works fine.
I also tried what's written here: http://msdn.microsoft.com/en-us/library/ms185298.aspx to no avail.
So is there some magic incantation nobody told me about to get it to work?
