Another one I haven't tested:

$sourceFile = 'C:\assets\Microsoft.Azure.ServiceFabric.WindowsServer.5.3.204.9494.zip'
$targetFolder = 'C:\Microsoft.Azure.ServiceFabric.WindowsServer'
 
[System.Reflection.Assembly]::LoadWithPartialName('System.IO.Compression.FileSystem')
[System.IO.Compression.ZipFile]::ExtractToDirectory($sourceFile, $targetFolder)
