无法在 Azure 网站中使用缓存

Question

我正在尝试在我的 Windows Azure 网站上使用缓存。缓存是在我的一个 Worker 角色上配置的。

我是从这篇文章开始的：http://www.windowsazure.com/en-us/develop/net/how-to-guides/cache/

最初，由于缺少程序集错误，我无法让 Azure 缓存客户端 dll 正常工作。

Could not load file or assembly 'Microsoft.WindowsAzure.ServiceRuntime, Version=1.7.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
Could not load file or assembly 'msshrtmi, Version=1.7.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

虽然这篇文章帮助我解决了这个问题：http://www.thedailyparker.com/PermaLink,guid,0be6425e-b509-4122-af01-7086ce2f811e.aspx

但接下来我会收到一个 SEHException，这听起来像是配置问题。虽然我不知道我错过了什么。 异常详情：

我希望有人能在正确的方向上帮助我。

您无法从网站访问 Windows Azure 缓存。您只能从 Web Role 或 Worker Role 访问它。

您是否在您的网站中尝试过Windows Azure Shared Caching？这应该可以（我自己还没有在网站上尝试过）。
