This project references NuGet package(s) that are missing on this computer

Question

I have an ASP.NET MVC5 application that worked yesterday and now I am getting this error when I try to build:

This project references NuGet package(s)

Answer 1

Is it possible that the packages have been restored to the wrong folder? Check that the paths in the csproj files are correct.

If they are different it could be caused by the packages now being restored to a different location. This could be caused by a NuGet.Config file being checked in specifying a node like this:

The packages are being restored, by the projects are still looking at the old location.
