aspnetcore/eng/scripts/AddAllProjectRefsToSolution.ps1

<#
.SYNOPSIS
This adds the complete closure of project references to a .sln file

.EXAMPLE
Let's say you have a folder of projects in src/Banana/, and a file src/Banana/Banana.sln.
To traverse the ProjectReference graph to add all dependency projects, run this script:

    ./eng/scripts/AddAllProjectRefsToSolution.ps1 -WorkingDir ./src/Banana/

.EXAMPLE
If src/Banana/ has multiple .sln files, use the -sln parameter.

    ./eng/scripts/AddAllProjectRefsToSolution.ps1 -WorkingDir ./src/Banana/ -SolutionFile src/Banana/Solution1.sln

            exit 1
