当SessionState with mode =“Custom”时，响应在此上下文中不可用

这是我在运行从Asp.net迁移到Windows Azure Cloud的Web项目时遇到的异常。如果web.config中的sessionstate

，那也工作得很好 
<sessionState mode="InProc" cookieless="false" timeout="30" />.

但是，如果我将web.config会话状态设为

<sessionState mode="Custom" customProvider="AzureCacheSessionStoreProvider" >
      <providers>
        <add name="AzureCacheSessionStoreProvider" type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache" cacheName="default" useBlobMode="true" dataCacheClientName="default"/>
      </providers>
    </sessionState>

它给出了以下异常。没有关于例外的线索。请尽早帮助。

例外：

感谢您的帮助，最后我找到了问题的原因。发生问题是因为我试图将System.Web.UI.WebControls存储到会话中。

由于并非所有System.Web.UI.WebControl都可以进行服务化，因此请避免将WebControl存储到会话中。

快乐编码..
