NGUI 3.5.9 build error on windows apps store

[MasashiWada]

Windows Store Apps is not available System.IO.File class.
You can UnityEngine.Windows.File.ReadAllBytes.

ByteReader.cs
   static public ByteReader Open (string path)
   {
      FileStream fs = File.OpenRead(path);

      if (fs != null)
      {
         fs.Seek(0, SeekOrigin.End);
         byte[] buffer = new byte[fs.Position];
         fs.Seek(0, SeekOrigin.Begin);
         fs.Read(buffer, 0, buffer.Length);
         fs.Close();
         return new ByteReader(buffer);
      }
      return null;
   }

More WSA/WS8 fun... Change this function to be:

1.         static public ByteReader Open (string path)
2.         {
3. #if UNITY_EDITOR || (!UNITY_FLASH && !NETFX_CORE && !UNITY_WP8)
4.                 FileStream fs = File.OpenRead(path);
5.  
6.                 if (fs != null)
7.                 {
8.                         fs.Seek(0, SeekOrigin.End);
9.                         byte[] buffer = new byte[fs.Position];
10.                         fs.Seek(0, SeekOrigin.Begin);
11.                         fs.Read(buffer, 0, buffer.Length);
12.                         fs.Close();
13.                         return new ByteReader(buffer);
14.                 }
15. #endif
16.                 return null;
17.         }

You can take a look at this repo:
https://github.com/windowsgamessamples/UnityPorting/tree/master/PlatformerPlugin/MyPluginUnity

It contains some useful thing for WP8/WSA. The thing is that in WP8/WSA everything as to be async and ReadAllByte is not. The functions in Legacy/System/IO/File.cs are using an async way. Try using these functions
