如何解决“缓存不支持此操作”。 Azure中的NHibernate缓存?

我正在尝试使用NHibernate.Caches.Velocity实现Nhibernate二级缓存,并使用此here on stack overflow讨论了this blog post

该应用程序是使用Nhibernate 3.2的Azure WebRole。

除了初始化会话工厂时抛出的异常外,一切似乎都是正确的:

"This operation is not supported by the cache."

堆栈追踪:

   at Microsoft.ApplicationServer.Caching.DataCacheFactory.CreateNewCacheClient(DataCacheDeploymentMode mode, String cacheName, NamedCacheConfiguration config, SimpleSendReceiveModule sendRcvModule)
   at Microsoft.ApplicationServer.Caching.DataCacheFactory.GetCache(String cacheName)
   at NHibernate.Caches.AppFabric.AppFabricCacheFactory.GetCache(String cacheName, Boolean useDefault)

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

Web.Config中:

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

有没有人知道造成这种情况的原因是什么?如果我谷歌它,我得到零相关结果。

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缓存不支持内部部署缓存的所有功能。我猜它正试图利用不支持的功能。 MS有一个list of the differences between the two
