我尝试使用会话状态提供程序将Azure托管缓存服务实现到我的解决方案中。目前我正在设置一个Session变量，只是在回发后检索它并且它是null。我可以使用DataCache对象将对象成功保存到缓存中，这告诉我在Web.config中正确配置了我的数据缓存设置，尽管我的会话状态配置设置可能需要微调。
相关的Web.config：
<sessionState mode="Custom" customProvider="AFCacheSessionStateProvider">
<providers>
<add name="AFCacheSessionStateProvider" type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache" cacheName="default" dataCacheClientName="default" applicationName="AFCacheSessionState" />
</providers>
</sessionState>
<dataCacheClients>
<dataCacheClient name="default">
<autoDiscover isEnabled="true" identifier="myEndpoint" />
<securityProperties mode="Message" sslEnabled="true">
<messageSecurity authorizationInfo="myKey" />
</securityProperties>
</dataCacheClient>
更新：我通过软件包管理器控制台（而不是通过GUI）重新安装了Microsoft.WindowsAzure.Caching，这产生了很多我通过GUI安装看不到的异常。

虽然它声明该软件包已成功安装，但这个巨大的异常列表让我停下来。我的安装出了什么问题，我该如何解决？
谢谢！
