当我改变这一行时：
<sessionState mode="Custom" customProvider="DefaultSessionProvider" timeout="15">
为：
<sessionState mode="InProc" customProvider="DefaultSessionProvider" timeout="15">
它工作正常，但我需要使用会话发布到Windows Azure。
任何人都可以帮助我或给我一些想法吗？
答案 0 :(得分：1)
让我们从这一部分开始：
当我改变这一行时：
<sessionState mode="Custom" customProvider="DefaultSessionProvider" timeout="15">为：
<sessionState mode="InProc" customProvider="DefaultSessionProvider" timeout="15">它工作正常，但我需要使用会话发布到Windows Azure。
进程外会话状态必须序列化，以便它可以跨越进程边界。例如，序列化使数据能够作为字节数组插入SQL Server表。
根据错误消息，对象图的序列化表示似乎有最大大小。此限制由特定提供商强制执行;其他ASP.Net提供商没有义务定义此限制。
经过一番挖掘后，我确认确实存在限制。
在DefaultSessionStateProvider中，位于System.Web.Providers.dll（Microsoft.AspNet.Providers包的一部分）中：
this.MaxSessionSize = ConfigurationManager.AppSettings["maxSessionSize"] == null
? 500000
: Convert.ToInt32(ConfigurationManager.AppSettings["maxSessionSize"],
(IFormatProvider) CultureInfo.InvariantCulture);
这会显示大小（500000），以及可能的更改方式（Azure可能会对此施加额外限制;我不知道。）
然而，还有一个更大的问题：你真的需要在会话中存储这么多数据吗？繁重的会议通常不是一个好主意。首先，想象一下因为每个页面请求序列化/反序列化500000字节对象图形而导致的处理负载。
答案 1 :(得分：1)
我提出的一个解决方案是对sessionState使用压缩：
<sessionState mode="Custom" customProvider="DefaultSessionProvider" compressionEnabled="true">
