历史 在我的开发环境中，我一直在与运行 Windows Azure 模拟器时反复出现的错误作斗争。在我创建基于 Azure 模板的新解决方案和项目之前解决，同时重新安装 2012 年 10 月更新 SDK。然后我不得不将所有文件复制到新项目中。在经历所有这些之前，因为我知道它可以工作，所以我想看看是否还有其他事情可以做。

设置

  • 视窗 8
  • Visual Studio 2012 更新 1
  • IIS Express 8
  • Windows Azure 工具 - 2012 年 10 月
  • Windows Azure 缓存 1.8.1.0
  • ASP.NET MVC 4.0 项目
  • Web 角色（2 个实例）
  • 缓存工作者角色（2 个实例）
  • 在缓存工作角色上启用缓存并设置为专用角色（本地角色状态为：UseDevelopmentStorage=true）
  • 会话使用分布式缓存
  • 输出缓存使用分布式缓存

Web.config 设置

    <sessionState mode="Custom" customProvider="AFCacheSessionStateProvider" cookieName="abc_session">
          <providers>
            <add name="AFCacheSessionStateProvider" type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache" cacheName="default" dataCacheClientName="default" applicationName="AFCacheSessionState" />
          </providers>
        </sessionState>

<outputCache defaultProvider="AFCacheOutputCacheProvider">
        <providers>
          <add name="AFCacheOutputCacheProvider" type="Microsoft.Web.DistributedCache.DistributedCacheOutputCacheProvider, Microsoft.Web.DistributedCache" cacheName="default" dataCacheClientName="default" applicationName="AFCacheOutputCache" />
        </providers>
      </outputCache>
    </caching>

  <dataCacheClients>
    <dataCacheClient name="default">
      <autoDiscover isEnabled="true" identifier="AppNameCacheWorkerRole" />
    </dataCacheClient>
  </dataCacheClients>

杂项注释：

  • 相同的配置在部署到 Azure 时运行良好，因此与我的本地环境有关。
  • 当我设置了多个 Web 角色实例时，IIS Express 崩溃了，我找到了运行 Visual Studio 2010 SP1 来解决的建议。我在系统上安装了 VS2010，因为一个工具（相信是 SQL）安装了它。安装 SP1 解决了 IIS Express 崩溃的问题，但随后再次出现此错误。
  • 如果我注释掉上面列出的 OutputCache 节点，错误就会消失。
  • 如果我将缓存工作人员角色从专用角色切换到并置角色，错误就会消失。

Spoke with Microsoft tech support and it appears this a known issue. Most of the time it can be resolved by forcing a refresh in the browser. I've had mixed success. The fix for this issue will be part of the next Azure SDK release.

This happens to me in production a lot! I upload my package to staging first, and have to always wait until all the instances are running before hitting the staging URL. Sometimes this error still occurs and I restart all my instances for it to fix itself.
