I have recently upgraded my SharePoint 2010 solution to SharePoint 2013 and in the same process upgraded the solution as well to Visual-Studio 2012.
One of the things I have observed is that I don't have the "deploy" option at each SharePoint project level. On digging a bit further I have noticed that the "deloy" option is available to all projects under solution but not for projects under any folder.
e.g. I have attached the image showing the solution structure containing two projects. As seen the "deploy" option is not available for the project under the folder.
Is this a bug or is there something setting in VS to make this work?
