First stab at powershell function to check if project has a package

gistfile1.txt

function Test-Project {
param(
  #The package we are looking for
  $PackageName
  )
  Process {
    $hasPackage = $false
    $packages = get-package $PackageName -First 1
    
    foreach ($package in $packages) {
      
      write-host "Checking $($package.Id) in $($_.ProjectName)"
      $PackageID = $package.Id
      $packageManager = $host.PrivateData.packageManagerFactory.CreatePackageManager()

      
        $fileSystem = New-Object NuGet.PhysicalFileSystem($_.Properties.Item("FullPath").Value) 	
        $repo = New-Object NuGet.PackageReferenceRepository($fileSystem, $packageManager.LocalRepository)

        foreach ($package in $repo.GetPackages() | ? {$_.Id -eq $PackageID}) {
          $hasPackage = $true;
        }
      
        
     }
     
     if($hasPackage) { $_ }   
  }
  
  
}
