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  that are missing on this computer   I have the two options checked that allow nuget to automatically download and install missing packages checked   turned ON  I have also tried deleting all of the files in the packages folder and then have nuget re-download them  Also when I open nuget and look for updates it says there are none that need to be installed  I can t figure what else to do to move beyond this amazingly annoying issue  I have also enabled nuget restore by right clicking the project and selecting that option  It then added a nuget folder and three items in that folder and does nothing to resolve the problem  I ve tried re-building and still get the same error

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.

I easily solve this problem by right clicking on my solution and then clicking on the Enable NuGet Package Restore option    P S  Ensure that you have the Nuget Install From Tools--  Extensions and Update--  Nuget Package Manager for Visual Studio 2013  If not install this extention first    Hope it helps

These are the steps I used to fix the issue   To add nuget packages to your solution    Right click on the project  not solution  you want to reference nuget  packages  Choose  Manage nuget packages On the popup window  on the left you have three choices   If you choose Online   Microsoft  amp   NET  you will be able to install Microsoft ASP NET Web API 2 2 package grouper  or whatever package  you need - mine was this   Now right click on your solution  not project  and choose Enable nuget package restore  This will cause the packages to be automagically downloaded at compilation

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      lt Import Project    MSBuildToolsPath  Microsoft CSharp targets    gt    After that line  I have to comment these out      lt Import Project    SolutionDir   nuget NuGet targets  Condition  Exists    SolutionDir   nuget NuGet targets      gt     lt Target Name  EnsureNuGetPackageBuildImports  BeforeTargets  PrepareForBuild  gt       lt PropertyGroup gt         lt ErrorText gt 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   lt  ErrorText gt       lt  PropertyGroup gt       lt Error Condition   Exists                 packages EntityFramework 6 4 0 build EntityFramework props    Text     System String   Format    ErrorText                    packages EntityFramework 6 4 0 build EntityFramework props       gt       lt Error Condition   Exists                 packages EntityFramework 6 4 0 build EntityFramework targets    Text     System String   Format    ErrorText                    packages EntityFramework 6 4 0 build EntityFramework targets       gt     lt  Target gt     lt Import Project                 packages EntityFramework 6 4 0 build EntityFramework targets  Condition  Exists                 packages EntityFramework 6 4 0 build EntityFramework targets      gt    Your solution will prompt that there was a change on your project  just select Reload All    Then everything works fine after rebuilding my solution

I had the same error but in my case it was not related to nuget packages at all  My solution had project that had reference to other projects that were not a part of my solution and were not built  After building them with some other solution  or I could include them into my solution as well   AND re-opening my solution in visual studio the issue was resolved

Editing  sln and  csproj is not always that easy or desirable  Once you get the error list you can see what projects have missing packages  also  the References node usually indicate that there are missing assemblies unless packages are source code  resources  images  or just text-based ones     Removing and then adding the packages is not a good idea unless you use the latest version of the package  Otherwise be prepared for surprises  not always pleasant ones   If  say  the package is EntityFramework then from NuGet gallery you get the latest version which at the time of writing this comment it is 6 1 3   So  maybe the safest way to handle the situation is to restore the missing packages one by one  Yes  a bit painful exercise but chasing subtle bugs due to different package version maybe much more unpleasant   Having this said  and let again EntityFramework be the missing package  you can issue the following command in the Package-Manager Console   PM gt  Install-Package EntityFramework -Version 6 0 1    This will install the correct version  that is 6 0 1  that is the one that is specified in packages config         lt  xml version  1 0  encoding  utf-8   gt       lt packages gt         lt package id  EntityFramework  version  6 0 1  targetFramework  net451    gt       lt  packages gt

In my case it happened after I moved my solution folder from one location to another  re-organized it a bit and in the process its relative folder structure changed   So I had to edit all entries similar to the following one in my  csproj file from     lt Import Project     packages Microsoft Bcl Build 1 0 14 tools Microsoft Bcl Build targets  Condition  Exists     packages Microsoft Bcl Build 1 0 14 tools Microsoft Bcl Build targets      gt    to     lt Import Project  packages Microsoft Bcl Build 1 0 14 tools Microsoft Bcl Build targets  Condition  Exists  packages Microsoft Bcl Build 1 0 14 tools Microsoft Bcl Build targets      gt     Note the change from    packages  to packages   It might be a different relative structure in your case  but you get the idea

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    lt add key  repositoryPath  value        Packages    gt    The packages are being restored  by the projects are still looking at the old location

The first thing to try is to right-click the solution and select  Restore Nuget Packages    In my case that did not work  so I followed some recommendations on deleting  Import  and  Target  on project file  this worked for 2 of my 3 projects  but got a different error on the last one   What worked was to open the Package Manager Console and run   Update-Package -reinstall -ProjectName MyProjectName   It takes some time but since it reinstall all packages your project will compile without problems
