xunit.core is incompatible with version of NuGet

I added a new project to the solution. I've added some nuget packages however it fails when building on TFS. It works fine when building locally. I get the following error messages:

 C:\Builds\8\Server-Dev-CI\src\.nuget\NuGet.targets (58): The schema version of 'xunit.core' is incompatible with version 2.0.30828.5 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.

When I open the sources in VS2013 (on the build server) I see the following: enter image description here

I have to click Restore Packages to get it to work. enter image description here

I already updated NuGet. Where is it getting " 2.0.30828.5 of NuGet" from???

Solution

  • I figured it out. The whole time I though TFS uses Visual Studio's NuGet, however it turns out TFS runs:

    C:\Program Files\Microsoft Team Foundation Server 12.0\Tools\nuget.exe restore

    I had to open up console and update nuget:

    nuget.exe update -self
