Visual-studio – Visual studio 2015 project missing all references

visual studiovisual-studio-2015

Starting from today, a WPF project that belongs to a solution with 20 projects, set all my references to missing

enter image description here

I've just checked the MS suggestion and the other answers on Stackoverflow but none worked…I've tried to re-get solution from SVN, with no luck, other colleagues haven't got this problem.
I've also tried to remove and re-add the references (System.Xml for example) .
But no way to make it work…

Any suggestion?
Thanks

Yes I use Nuget, the other 19 points to the same assemblies …nothing has been moved

UPDATE #2

Since I was not able to proceed I've copied the project from a colleague and now it works…. think something went wrong in the filesystem…have compared the solution and they were identical

The resolution to this issue is.

Whenever you import a project to VS 2015 it modifies your .csproj. So, in order to fix it. Right click on .csproj and open it in notepad or any editor and delete the following

<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>

Then build your solution and it should work.
