title: Copy files to solution folder with init.ps1 and nuget
body: <p>I am having trouble with ps script in init.ps1 of nuget package.  I am trying to create a solution folder upon install of the package AND then copy dlls/pdbs to this folder (and delete  the source dll/pdbs installed by the package in the project).
  I am able to create the solution folder, but am having trouble copying the files from the \content\temp directory to the solution folder.
  In fact, i really want a real folder on the filesystem and a solution folder to match, so the copy should copy the files to the real file system folder and then be added to the solution folder.<br>
  The copy portion is not working and I am not getting any output errors.  Bit lost.</p>

  $parentProject = $solution.AddSolutionFolder("MyDlls")
  
  # Create a child solution folder.
  $parentSolutionFolder = Get-Interface $parentProject.Object ([EnvDTE80.SolutionFolder])
  
  $fileName = (Join-Path $installPath "\temp\mydll")
  $projectFile = $parentSolutionFolder.AddFromFile($fileName)
