Question

我开始重复抛出Azure缓存错误。它似乎与过期的会话有关。这是一个随机样本 - 它发生在静态文件中。

此处没有代码，它在web.config中配置

<dataCacheClients>
  <dataCacheClient name="default">
    <hosts>
      <host name="[mycachename]" cachePort="22233" />
    </hosts>
    <securityProperties mode="Message">
      <messageSecurity authorizationInfo="[mykey]"></messageSecurity>
    </securityProperties>
  </dataCacheClient>
  <dataCacheClient name="SslEndpoint">
    <hosts>
      <host name="[mycachename]" cachePort="22243" />
    </hosts>
    <securityProperties mode="Message" sslEnabled="true">
      <messageSecurity authorizationInfo="[mykey]"></messageSecurity>
    </securityProperties>
  </dataCacheClient>
</dataCacheClients>

编辑：会话状态配置如下：

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

我试图了解是否存在 a）我可以做任何事情来解决这个问题 b）涉及哪个DLL，以及最新版本是什么（所以我可以看看更新是否有帮助） c）如果有人看到这个。

它是在我做了很多应用程序更新之后开始的，并且还更新了Azure中的缓存大小。因此不确定原因是什么。我不会认为代码更改是负责任的，但我们可能已经更新了一些DLL，因为我们在开发过程中使用的PC之一是新构建的。

Answer 1

我通过nuget更新了azure.caching和azure.configuration，然后重新发布，错误现在已经消失，没有其他代码或配置发生变化，所以看起来这是某个DLL版本之间的不兼容。
