  <p><code>You are trying to build with OctoPack, but the NuGet targets file that OctoPack depends on is not available on this computer. This is probably because the OctoPack package has not been committed to source control, or NuGet Package Restore is not enabled</code></p>
  
  <p>According to this link <a href="https://octopusdeploy.com/blog/octopack-3.0" rel="noreferrer">https://octopusdeploy.com/blog/octopack-3.0</a> I need to make some changes to get package restore working properly, but another link within the previous one says that no configuration is required if using VS2013 and Visual Studio Online <a href="http://docs.nuget.org/docs/reference/package-restore-with-team-build" rel="noreferrer">Nuget.org</a></p>
  
  <p>When I build in VS all of the packages get restored first and then the project builds. Also if I build the project and invoke Octopack via command line everything works fine. Thoughts?</p>
