just tried with VS 2015, update 1 community edition
created a new project for class libraries
added vvvv package source
had to uncheck include prerelease to get vvvv.plugininterfaces in the list.
installing took forever
had to set configuration to x64 or x86 (not AnyCPU)
guessing from the pic you uploaded (no zoom in on this page??) your configuration is AnyCPU.
does it work if you change that to a dedicated architecture?
