I deleted the exported zip file that was placed in my exported templates folder and of course it still shows in Visual Studio\'s \"Add New Project\" dialog. I expected that but
After manually searching for some of the custom profile templates(.vstemplate),I found them at the following location:
%userprofile%\AppData\Local\Microsoft\VisualStudio\10.0\Extensions
It appears VS2010 installs some of the templates as extesions or the authors made it that way.I hope this helps someone.
May need to run "devenv /setup" at the run command to refresh the VS2010 after you delete the templates.
