I am encountering the error during the Build phase of an Azure Pipeline on the Azure DeveOps site. Specifically, the packages it is complaining about are:

I have looked at similar questions where the solution is to perform a Nuget restore but they usually refer to a local machine or a Visual Studio installation not Visual Studio Team Services (the previous name for Azure DevOps).

In this case, the computer is a Hosted 2017 Agent in the Azure DevOps environment and I don't see how get a Nuget Restore job to execute there.

However, earlier in the log file, I do see references to where the build agent is installing the required Nunit Nuget packages:

  • You need to run [`dotnet restore`](https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/build/dotnet-core?view=vsts#restore-nuget-packages) command before your build in order to install all the required package – Jayendran Oct 01 '18 at 01:45
  • Did you ever find a solution to this? I'm hitting the same issue. – htxryan Feb 13 '19 at 17:25
  • Any help? met the same too – John Jang May 22 '19 at 11:26

It's a known Nuget issue

Look here

The solution is, in your test project's .csproj file, at the bottom normally, you'll find a section 

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>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}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('..\packages\NUnit.3.12.0\build\NUnit.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\NUnit.3.12.0\build\NUnit.props'))" />
  </Target>

Delete that section.

  • I ran into this error today on a brand new project and this fixed it for me, so apparently over a year later this remains an issue. – Synctrex Jul 16 '20 at 14:17
  • No need to delete entire section; only to "the paths that were pointing to where those two used to be" as Rod answer below – Marcelo Scofano Diniz Jul 13 '21 at 00:43

For what it's worth, I solved the problem by removing the erroneous tags in the Target tag. This is what I initally had in my .csproj file:

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>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}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('packages\EntityFramework.6.4.4\build\EntityFramework.props')" Text="$([System.String]::Format('$(ErrorText)', 'packages\EntityFramework.6.4.4\build\EntityFramework.props'))" />
    <Error Condition="!Exists('packages\EntityFramework.6.4.4\build\EntityFramework.targets')" Text="$([System.String]::Format('$(ErrorText)', 'packages\EntityFramework.6.4.4\build\EntityFramework.targets'))" />
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.props'))" />
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.targets'))" />
</Target>

I looked at it and realized that the two lines that had !Exists('packages\EntityFramework.6.4.4... were pointing to where those two used to be, before I moved the project. So, I deleted them. Now I have this:

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>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}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.props'))" />
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.targets'))" />
</Target>

This got rid of the error in Azure DevOps Services Pipeline. It now builds with no errors.

Make sure that the "Restore NuGet Packages" Option is checked on your pipeline "Build" step:

  • I don't think this is correct. If you click the "i" icon next to the Restore NuGet Packages line, you'll see Microsoft has noted `This option is deprecated. To restore NuGet packages, add a NuGet Tool Installer task before the build.` This option has no impact. – Synctrex Jul 16 '20 at 14:08
