Auto restore Nuget packages with TFS Build (Useful for non Visual studio environment like test server)

Procedure to enable automatic nuget restore in VS 2015/2017

> Create a folder with name ".nuget" in the solution root

> Add these 3 files in to ".nuget folder"
1. "nuget.config"
2. "NuGet.exe"
3. "NuGet.targets"

> Add these tag in you all project file by using node pad or by VS(unload project to edit)

1. <NuGetPackageImportStamp></NuGetPackageImportStamp>
    <RestorePackages>true</RestorePackages>

Add this entry inside "<PropertyGroup>" tag.

2. <Import Project="$(SolutionDir)\.nuget\NuGet.targets" />
  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
  </Target>

Add this in "<project>" tag & would be good if these all enties added in ending of tag.

> This step is addtional but recomemded sometimes.
Add a file with named "repositories.config" inside packages folder & refer all libraries "packages.config". if libraries dont have "packages.config", then no need to refer those.

eg:- <?xml version="1.0" encoding="utf-8"?>
<repositories>
  <repository path="..\Myportal\packages.config" />
  <repository path="..\Myportal.UnitTests\packages.config" />
  <repository path="..\\Myportal.Core\packages.config" />
</repositories>

Here "Myportal" is example taken to represnt library.
