Visual-studio – This project references NuGet package(s) that are missing on this computer

Bring up the Package Manager Console in Visual Studio - it's in Tools / NuGet Package Manager / Package Manager Console. Then run the Install-Package command:

Install-Package Common.Logging -Version 1.2.0

See the command reference for details.

Edit: In order to list versions of a package you can use the Get-Package command with the remote argument and a filter:

Get-Package -ListAvailable -Filter Common.Logging -AllVersions

By pressing tab after the version option in the Install-Package command, you get a list of the latest available versions.

I didn't look very well, there's another property added to the project files:

<RestorePackages>true</RestorePackages>

Just have to remove this as well as all these lines manually from all *.csproj files:

  <Import Project="$(SolutionDir)\.nuget\nuget.targets" />

UPDATE:

Turns out it's a persistent little bugger, if you're manually editing your project files, make sure to close the solution and delete all the lines from the project at once, otherwise they're just added again once the project reloads...

UPDATE2:

Delete the .nuget folder from the solution root too

UPDATE3:

A later version of NuGet adds another section that you need to remove:

 <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>

Update4

Inside the NuGet.Targets located in the .nuget folder, there is another section that gets added to new projects... switch it to false.

<!-- We need to ensure packages are restored prior to assembly resolve -->
<BuildDependsOn Condition="$(RestorePackages) == 'false'">
    RestorePackages;
    $(BuildDependsOn);
</BuildDependsOn>
