Ionic.BZip2.CF (DotNetZip) assembly fails to load in WP8 using Unity 4.5.1p2

Hi, this is working when building with Unity 4.3.4f1 but now the following exception is thrown at runtime when trying to use the assembly.

An exception of type 'System.IO.FileLoadException' occurred in Assembly-CSharp.DLL but was not handled in user code
Additional information: Could not load file or assembly 'Ionic.BZip2.CF, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The version properties in Visual Studio Express 2013 Windows shows 1.9.1.8 although inspecting the dll with ILSpy before and after processing by Unity reveals the PublicKeyToken is set to null.

 

There are two references in Assembly-CSharp to Ionic.BZip2CF, one with null public key and one with the original value. I've just reproduced this and the issue in an empty project by having some code instantiate a BZip2OutputStream.

Example code:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using Ionic.BZip2;
5. using System.IO;
6.  
7. public class BzipTest : MonoBehaviour {
8.  
9.     // Use this for initialization
10.     void Start () {
11.         byte[] bytes = new byte[10];
12.         byte[] compressed = CompressBytes(bytes);
13.     }
14.  
15.     public static byte[] CompressBytes(byte[] bytes)
16.     {
17.         using (MemoryStream memoryStream = new MemoryStream())
18.         {
19.             WriteCompressedBytes(bytes, memoryStream);
20.            
21.             byte[] compressedBytes = memoryStream.ToArray();
22.             return compressedBytes;
23.         }
24.     }
25.    
26.     public static void WriteCompressedBytes(byte[] bytes, Stream toStream)
27.     {
28.         using (BZip2OutputStream stream = new BZip2OutputStream(toStream))
29.         {
30.             stream.Write(bytes, 0, bytes.Length);
31.             stream.Flush();
32.         }
33.     }
34.    
35.     // Update is called once per frame
36.     void Update () {
37.    
38.     }
39. }
40.  

 

Thanks. Here's the bug report: http://fogbugz.unity3d.com/default.asp?616138_6ljqjtqvo2kd6bj2
