title: C# Usage of ZipArchive crashes the programm
body: <p>I'm trying to unzip files without providing an extra *.dll.
  For that reason, i'm using the ZipArchive class from System.IO.Compression.</p>
  
  <p>I added System.IO.Compression &amp; System.IO.Compression.FileSystem as a reference and on my own computer, everything works fine. However, friends can't use it, because it crashes on the line</p>
  
  <pre><code>ZipArchive archive = ZipFile.Open(local, ZipArchiveMode.Read);
  </code></pre>
  
  <p>Do I need to provide an extra *.dll for it to work?
  Whats the problem?</p>
