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

I had the same issue when i reference the Class library into my MVC web application,

the issue was the nuget package version number mismatch between two projects.

ex: my class library had log4net of 1.2.3 but my webapp had 1.2.6

fix: just make sure both the project have the same version number referenced.
