NuGet Packages are missing

Question

I searched this problem but none of the solutions worked  I have Visual Studio Professional 2015 installed and I am using TFS  My NuGet version is 3 1 6  This problem is happening only in my C  Web API MVC project   I am getting the below error      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      packages Microsoft Net Compilers 1 0 0 build Microsoft Net Compilers props    I do not have  nuget folder in my solutions  I have a packages folder in the solution and when I delete it  it seems like NuGet does rebuild the dependencies but the project still has the above error  I tried removing the project from TFS and it didn t fix it  Along with the above error  all the references in the project have yellow warning signs and say they are missing  When I checked the NuGet Package Manager for the project  everything that is  missing  has a green tick next to it  including Microsoft Net Compilers  I tried adding a new Web API MVC project and it faced a similar problem where most references such as Owin were  missing  with the yellow warning sign

I had this exact frustrating message   What finally worked for me was deleting all files and folders inside  packages and letting VS re-fetch everything the next build

I was having the same issue  it turns out one of the projects I was referencing was outside the solution directory  and therefore didn t share the same   packages  folder   The solution that worked for me was to open the reference project s solution and build it there  Once that project built  the errors went away

The error message is completely correct  I tried all the tricks and none worked  The project  simple MVC Web App test  moved from Windows 8 1 VS 2015 Community to my new test box on Windows 10  All the latest updates to VS 2015 applied  I could not even install any newer version of the compilers package   Loop   lt LOOP gt This seems to be a Ground Hog Day phenomena  lt  LOOP gt  GoTo Loop   I finally just copied Microsoft Net Compilers 1 0 0 from the old project into the new one and it worked  I could then start to update other packages to newer version  Looks like a nuget project upgrade process bug to me   NOTE  The original project was created in VS 2015 and does not have any legacy nuget methodologies

BEWARE - this updates packages for the entire solution not just the project  If you have one more missing nuget package that giving your error while building your solution use following command using Nuget Command Console from Tools  gt  Nuget Package Manager  gt  Package Manager Console  It will reinstall your all current packages  Update-Package    reinstall  Update  You can pass specific project name as a parameter  Update-Package    reinstall -ProjectName SampleApp

For me  the packages were there under the correct path  but the build folders inside the package folder were not   I simply removed all the packages that it said were missing and rebuilt the solution and it successfully created the build folders and the  props files   So the error messages were correct in informing me that something was a miss

Not sure if this will help anyone  but I had this issue come up when I deleted the source code from my local machine without having ever saved the solution file to TFS    During initial development  I was right-clicking and checking in the project in Solution Explorer  but forgot to ever check in the solution itself    When I needed to work on this again  all I had in TFS was the  csproj file  no  sln file   So in VS I did a File --  Source Control --  Advanced -- Open from Server and opened the  csproj file   From there I did a Save All and it asked me where I wanted to save the  sln file   I was saving this  sln file to the project directory with the other folders  App Data  App Start  etc    not the top level directory   I finally figured out that I need to save the  sln file up a directory from the project folder so it s on the same level as the project folder   All my paths resolved and I was able to build it again

For anyone who stumbles here with the issue I had  some but not all packages being restored on a build server   the final piece of the puzzle for me was adding a NuGet config in the root of my solution  sibling to the  SLN file as David Ebbo explained here  http   blog davidebbo com 2014 01 the-right-way-to-restore-nuget-packages html   From Ebbo s blog post  the file contents for me are simply   lt  xml version  1 0  encoding  utf-8   gt   lt configuration gt     lt packageSources gt       lt add key  nuget org  value  https   www nuget org api v2     gt     lt  packageSources gt   lt  configuration gt    UPDATE   The NuGet API URL has changed for v3  current as of Sept 2016   From https   www nuget org    lt add key  nuget org  value  https   api nuget org v3 index json    gt

A different user name is the common cause for this  Nuget downloads everything into   C  Users USER NAME source repos  and if you had the project previously setup on a different user name the  csproj file may still contain that old user name there  simply open it and do a search replace for  C  Users  OLD USER NAME source repos  to  C  Users NEW USER NAME source repos

The issue for me was that NuGet couldn t automatically get update the packages because the full file path would be too large  Fixed by moving my solution to a folder in my Documents instead of a deeply nested folder   Then can right-click on solution and select  Restore NuGet Packages   which probably isn t necessary if you just build it and let it do it for you   and then select  Manage NuGet Packages for Solution  to get all the packages updated to the latest version   This was for a solution of a sample ASP MVC application downloaded from Microsoft s web site

You also get this error if you use package config together with this build command  MSBuild exe  t Restore MySln sln   In this case either switch to nuget restore command or use PackageReference

To expand on a few of the answers here  yes you could remove the following block from your  csproj file    lt Target Name  EnsureNuGetPackageBuildImports  BeforeTargets  PrepareForBuild  gt   and this fixes the issue  however in my case  I noticed that I had additional references to the  NET Compilers and  CodeDom Providers with different versions    lt Error Condition   Exists     packages Microsoft Net Compilers 1 0 0  lt Error Condition   Exists     packages Microsoft CodeDom Providers DotNetCompilerPlatform 1 0 0    lt Error Condition   Exists     packages Microsoft Net Compilers 2 0 1  lt Error Condition   Exists     packages Microsoft CodeDom Providers DotNetCompilerPlatform 1 0 3    When my packages config only referenced the following    lt package id  Microsoft Net Compilers  version  2 0 1   lt package id  Microsoft CodeDom Providers DotNetCompilerPlatform  version  1 0 3    Removing the 1 0 0 items from the  csproj file fixed the issue

I had the same error  missing exactly the same package  today  I also created a MVC   Web API project   It happend because I moved the app files  including the  csproj  file to another location  I manually updated the  sln file but all packages dependencies are now  Visual Studio 2015  stored in  csproj file    Editing the  csproj file and correcting the relative path to the solution folder  which contains the packages folder  solved the problem for me

As many suggested removing the  lt Target gt  tag may make it compile-able  Yet  beware of the fact that it has a side effect when you do it for test projects    I got error related to MSTest TestAdapter nuget package while compiling  Resolved that issue by removing  lt Target gt  tag  Though it made build successful  test methods became non discover-able  Test explorer won t list down the test methods in that project and Run Test or Debug Test won t work as well    I encountered this while using Visual Studio 2017 and  Net framework 4 7  it can very well happen in other versions

For DevOps build engineers  you can probably fix this running nuget restore against the affected SLN  or project if you lack a SLN  I have to do this for our CI CD builds for all our UWP projects    Make sure nuget is installed on the build slave either in Visual Studio or standalone  If it s the latter  make sure it s in PATH and skip step 2  Either open the VS Dev CMD console  or load it via an already open one  which you can do with the instructions below  VS2015 call   VS140COMNTOOLS VsDevCmd bat  or VS2017 call   ProgramFiles x86   Microsoft Visual Studio 2017 Enterprise Common7 Tools VsDevCmd bat    call nuget restore MyStuff SLN or call nuget restore MyStuff csproj if there s no SLN
