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 have the same issue. I encountered it when I copied an existing project and transferred it on the folder of my solution directory and added it as existing project to my empty solution. So I have to edit my csproj file and look for this specific line of code, most of the time, this is can be found on the last lines:

After that line, I have to comment these out:

  
  
    
      This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.
    
    
    
  
  

Your solution will prompt that there was a change on your project, just select Reload All:

Then everything works fine after rebuilding my solution.
