c# - 如何解决Azure中NHibernate缓存的 "This operation is not supported by the cache."问题？

Question

我正在尝试使用 NHibernate.Caches.Velocity 实现 Nhibernate 二级缓存并讨论 here on stack overflow使用这个this blog post .

该应用程序是使用 Nhibernate 3.2 的 Azure WebRole。

除了初始化 session 工厂时抛出的异常之外，一切似乎都是正确的:

"This operation is not supported by the cache."

   at FluentNHibernate.Cfg.FluentConfiguration.BuildSessionFactory() in d:\Builds\FluentNH\src\FluentNHibernate\Cfg\FluentConfiguration.cs:line 230

网络配置:

  <dataCacheClients>
    <dataCacheClient name="default">
      <hosts>
        <host name="xxx.cache.windows.net" cachePort="22233" />
      </hosts>
      <securityProperties mode="Message">
        <messageSecurity
          authorizationInfo="xxx">
        </messageSecurity>
      </securityProperties>
    </dataCacheClient>
  </dataCacheClients>

有谁知道这是什么原因造成的吗？如果我用谷歌搜索，我得到的相关结果为零。

我不能肯定地说，因为我不熟悉 NHibernate 尝试使用缓存的方式，但 Azure 缓存不支持本地缓存的所有功能。我猜想它正在尝试利用不受支持的功能。 MS有一个list of the differences between the two
