visual studio - What does this warning triangle means? -


i'm creating .net core 2.0 web application in visual studio 2017, in dependencies, have these yellow triangles. there's no info it. mean? enter image description here

it means assembly (dll) can't found in location should be. because assembly didn't compile, or performed clean , external reference removed, or other reasons depending on project structure.

in case need check have correct dot.net entity framework core (ensure core, v6 , since normal 'entity framework' not core compatible) installed.

oh, , warning triangles on items above carried main issue marked deeper down tree.

hope helps
