If you only need to uncompress zip file, You don't need to add an external third party library.

Only you need is Add a reference to Microsoft Shell controls and Automation from the COM tab in the Reference Manager in Visual Studio.

private static void Unzip(String sourceFile,String destination) 
{
    Shell32.ShellClass sc = new Shell32.ShellClass();
    Shell32.Folder SrcFlder = sc.NameSpace(sourceFile);
    Shell32.Folder DestFlder = sc.NameSpace(destination);
    Shell32.FolderItems items = SrcFlder.Items();
    DestFlder.CopyHere(items, 20);          
}

With this, you don't have to distribute any additional dll file with your application.
