Visual-studio – NuGet Packages are missing

nugetvisual studiovisual-studio-2015

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

  1. I do not have .nuget folder in my solutions.
  2. 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.
  3. I tried removing the project from TFS and it didn't fix it.
  4. Along with the above error, all the references in the project have yellow warning signs and say they are missing.
  5. 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.
  6. 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 solved my issue by removing this code from .csproj file:

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
  <PropertyGroup>
    <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
  </PropertyGroup>
  <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>
