Disable the NuGet Package Restore functionality in a Visual Studio solution.

@PilotBob I don't have any experience with .vbproj files, but I would guess that it is very similar (possibly just changing line 45) to search for that extension.

Thanks for the share. Much appreciated.

I had hoped that this script would do all the steps of the migration guide (http://docs.nuget.org/docs/workflows/migrating-to-automatic-package-restore). It did remove the ".nuget" folder from .sln and disk, and also removed the

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

section, but did not remove the:

<RestorePackages>true</RestorePackages>

and

  <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>
  </Target>

sections for me. Perhaps i skipped/missed something?

@automatonic I have not seen those sections before, which is why they are not accounted for in the script. Should be easy to add though.

Hi, thanks for sharing! I found a problem when OctoPack installed.
