The ZipFileExtensions class contains only static methods that extend the ZipArchive and ZipArchiveEntry classes. You do not create an instance of the ZipFileExtensions class; instead, you use these methods from instances of ZipArchive or ZipArchiveEntry.

To use the extension methods, you must reference the System.IO.Compression.FileSystem assembly in your project. The System.IO.Compression.FileSystem assembly is not available in Windows Store apps. Therefore, the ZipFileExtensions and ZipFile classes (both of which are in the System.IO.Compression.FileSystem assembly) are not available in Windows Store apps. In Windows Store apps, you work with compressed files by using the methods in ZipArchive, ZipArchiveEntry, DeflateStream, and GZipStream.

The ZipFileExtensions class contains three methods that extend ZipArchive:

The ZipFileExtensions class contains two methods that extend ZipArchiveEntry:
