param($PackageID)

$packageManager = $host.PrivateData.packageManagerFactory.CreatePackageManager()

foreach ($project in Get-Project -all) {
	$fileSystem = New-Object NuGet.PhysicalFileSystem($project.Properties.Item("FullPath").Value) 	
	$repo = New-Object NuGet.PackageReferenceRepository($fileSystem, $packageManager.LocalRepository)

	foreach ($package in $repo.GetPackages() | ? {$_.Id -eq $PackageID}) {
		Update-Package $package.Id -Project:$project.Name 
	}
}

I just read the first line in the description: "Script to upgrade all NuGet packages in solution to last version" and assumed it updated all packages to there latest version I none argument was given on the line.

Yes, Now I know that for sure and I will be looking at both NuGetPackageUpdater and have allready voted on Haacked's blog.

But still thanks very much for this script since it still helped me.
