I have a rather old SharePoint project that I believe goes back to SP2007, and is currently working fine with SP2010. My current process for creating a .wsp for sp2010 is to use WSPBuilder. It seems that WSPBuilder is not compatible with SP2013/.net4.
What can I do to 1) have VS13 build a wsp, this old project needs to be migrated into an SP2013 project? or 2) can I create the wsp manually or through a plugin like WSPBuilder?
