已編譯的DLL中的序列化異常

我已經繼承了一個電子商務ASP.NET（後面的c＃代碼）web應用程序。我們最近移動了服務器，這證明有些麻煩。我對IIS服務器配置和處理這樣的大型項目的經驗很少。現在大部分問題已經得到解決，但我們遇到了關鍵部分的問題，因爲客戶試圖進行支付。
隨着客戶確認付款後，應用程序可能會遇到以下錯誤：已編譯的DLL中的序列化異常

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET 
will serialize the session state objects, and as a result non-serializable objects or 
MarshalByRef objects are not permitted. The same restriction applies if similar 
serialization is done by the custom session state store in 'Custom' mode.

堆棧跟蹤：

[SerializationException: Type 'PayerAuthentication.PayerAuthenticationServicePost' in Assembly 'PayerAuthentication, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.] 
    System.Runtime.Serialization.FormatterServices.InternalGetSerializableMembers(RuntimeType type) +7733643 
    System.Runtime.Serialization.FormatterServices.GetSerializableMembers(Type type, StreamingContext context) +258 
    System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitMemberInfo() +111 
    System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitSerialize(Object obj, ISurrogateSelector surrogateSelector, StreamingContext context, SerObjectInfoInit serObjectInfoInit, IFormatterConverter converter, ObjectWriter objectWriter) +161 
    System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.Serialize(Object obj, ISurrogateSelector surrogateSelector, StreamingContext context, SerObjectInfoInit serObjectInfoInit, IFormatterConverter converter, ObjectWriter objectWriter) +51 
    System.Runtime.Serialization.Formatters.Binary.ObjectWriter.Serialize(Object graph, Header[] inHeaders, __BinaryWriter serWriter, Boolean fCheck) +410 
    System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Serialize(Stream serializationStream, Object graph, Header[] headers, Boolean fCheck) +134 
    System.Web.Util.AltSerialization.WriteValueToStream(Object value, BinaryWriter writer) +1577

谷歌搜索結果表明我要補充[Serializable]受影響的類聲明，但這是一個編譯的DLL，我沒有csproj。代碼在以前的服務器上工作正常，我不相信已對代碼進行了任何更改，僅限於web.config - 我該怎麼辦？

的web.config將sessionState部讀取<sessionState mode="StateServer" />

UPDATE1：使用反射器，我導出類的上方，使得它可序列化，重新編譯並替換該DLL。訂單過程更進一步，因此我遇到了另一個DLL編譯類相同的錯誤。我再次能夠使用Reflector查看代碼，然後將其導出，編輯和重新編譯。
現在我有中出現同樣的錯誤：

SerializationException: Type 'System.Runtime.Remoting.Messaging.AsyncResult' in Assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.]

我不知道我能做到這事，因爲這必須是.NET系統文件的一部分！還有什麼想法？

UPDATE2：哈，嗯，我後來發現它是正確處理費，但隨後投擲System.Runtime.Remoting.Messaging.AsyncResult上述Unable to serialize the session state錯誤用戶得到交易的收據之前。不好。不確定現在該怎麼往前走......

UPDATE3：我試圖創建System.Runtime.Remoting.Messaging.AsyncResult類的副本，並使其可序列化，但隨後這是導致不一致的可訪問性問題。

using System; 
using System.Runtime.InteropServices; 
using System.Threading; 
using System.Security.Permissions; 
using System.Runtime.Remoting.Messaging; 

    [Serializable, ComVisible(true)] 
    public class myAsyncResult : IAsyncResult, IMessageSink 
    { 
     // Fields 
     private AsyncCallback _acbd; 
     private Delegate _asyncDelegate; 
     private object _asyncState; 
     private ManualResetEvent _AsyncWaitHandle; 
     private bool _endInvokeCalled; 
     private bool _isCompleted; 
     private IMessageCtrl _mc; 
     private IMessage _replyMsg; 

     // Methods 
     internal myAsyncResult(Message m); 
     //[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)] 
     public virtual IMessageCtrl AsyncProcessMessage(IMessage msg, IMessageSink replySink); 
     private void FaultInWaitHandle(); 
     public virtual IMessage GetReplyMessage(); 
     public virtual void SetMessageCtrl(IMessageCtrl mc); 
     //[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)] 
     public virtual IMessage SyncProcessMessage(IMessage msg); 

     // Properties 
     public virtual object AsyncDelegate { get; } 
     public virtual object AsyncState { get; } 
     public virtual WaitHandle AsyncWaitHandle { get; } 
     public virtual bool CompletedSynchronously { get; } 
     public bool EndInvokeCalled { get; set; } 
     public virtual bool IsCompleted { get; } 
     public IMessageSink NextSink { [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)] get; } 
    }

具體而言，即error CS0122: 'System.Runtime.Remoting.Messaging.Message' is inaccessible due to its protection level。我可以看到這是因爲Message是一個內部類。但是當然，我無法更改它的可訪問性級別，因爲它是System.Runtime命名空間的一部分。並且複製並重命名它會再次導致同樣的問題，當然？
現在任何人都可以幫我嗎？

最後更新 看起來，這一切後，這是SSL證書（見我的回答如下）
