DotCMIS/Alfresco：调用GetRootFolder时出现“XML文档错误”

Question

With DotCMIS我可以成功启动会话到Alfresco 4.0.1 CMIS服务器。
但是当我打电话session.GetRootFolder()，我得到下面的异常：

的一个重要组成部分似乎是：Read by order only possible for encoded/bare format

我的代码是从the tutorial几乎直：

using System; 
using System.Collections.Generic; 
using DotCMIS; 
using DotCMIS.Client.Impl; 
using DotCMIS.Client; 
using DotCMIS.Data.Impl; 
using DotCMIS.Data.Extensions; 
namespace tests.sln 
{ 
    class MainClass 
    { 
     public static void Main (string[] args) 
     { 
      // Connect to repository 
      Dictionary<string, string> parameters = new Dictionary<string, string>(); 
      parameters[SessionParameter.BindingType] = BindingType.AtomPub; 
      parameters[SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/cmisatom"; 
      parameters[SessionParameter.User] = "admin"; 
      parameters[SessionParameter.Password] = "admin"; 
      SessionFactory factory = SessionFactory.NewInstance(); 
      ISession session = factory.GetRepositories(parameters)[0].CreateSession(); 
      Console.WriteLine("Created CMIS session: " + session.ToString()); 

      // Get the root folder 
      IFolder rootFolder = session.GetRootFolder(); // Error happens here 
     } 
    } 
} 

什么我错过了吗？

在调试模式下，我可以在堆栈中看到DotCMIS.Client.Impl.Session.GetObject (objectId="workspace://SpacesStore/77acb21f-811c-49a3-be4d-5cc7f177f461"，不确定它的含义，但77acb21f-811c-49a3-be4d-5cc7f177f461确实是Alfresco的company_home的节点引用。

如果我在上面的代码中将URL更改为http://localhost:8080/alfresco/service/cmisatom，则Not Found错误会在前面出现在GetRepositories行。所以我很确定我的网址是正确的。

我下载了DotCMIS源代码，现在正在Monodevelop中进行调试。

使用Wireshark我已经确定为例外发生在包：

您使用的是旧的Alfresco CMIS URL。

检查：
