使用 Windows Azure缓存与模拟器(即在本地,而不是云)时遇到问题.

我的系统配置是：

> Windows 8
> Visual Studio 2012 Update 1
> Azure SDK和Emulator 1.8
> Windows Azure缓存1.8.1
> Web API
> .NET 4.5

问题是：我们的服务器利用(角色中)Windows Azure缓存进行会话管理等.一旦服务器从客户端获得请求,它就开始与Windows Azure缓存通信以放置/获取一些对象(例如,会话对象).然后发生“超时”异常(Microsoft.ApplicationServer.Caching.DataCacheException),服务器无响应,在Visual Studio的输出日志中显示以下消息.

当这开始发生时,服务器刚刚关闭(即运行,但没有响应).

知道为什么会这样吗？它与Windows 8有关吗？

谢谢,

我也遇到了这个问题,并将其追溯到一台机器上的Hyper-V虚拟以太网适配器.禁用我安装的两个适配器修复了Azure缓存中的超时错误.在这台机器上,我可以继续保持与网络/互联网的连接.

在另一台机器上没有安装Hyper-V,并且禁用以太网适配器(断开与互联网的连接)“修复”了这个问题.因此,要运行我的应用程序,我必须首先断开与网络的连接.

在这两台机器上,开发Azure缓存在执行缓存服务器的IP查找(例如127.255.0.0,127.255.0.1,127.255.0.2等)时似乎有问题,它适用于一些请求,然后开始超时.当与网络断开连接时,它始终有效.

在我开始遇到问题之前,这两台Windows 8机器上的这个工作正常.

更新

刷新DNS缓存为我解决了这个问题,现在它可以在连接到网络时运行. ipconfig / flushdns
