For whatever reason, if you go to publish on the Nop.Web you will find that the default FolderProfile target location has this directory saved. Just create a new profile with your settings and delete this one. Clean the solution, close VS, delete the vs folder and the bin, obj folders from the project folders via explorer. Restart VS and rebuild solution. VS will replace the vs, bin, obj folders. Publish the project with your profile and upload the newly published files. Its just left overs from the Andrei builds prior to releasing the code on github.
