具有瞬态故障处理的Azure Web角色阻止例外:完全限定后路径太长

Question

我们将云瞬态故障处理块应用于云服务的Web角色,我们甚至没有编写一个单行代码.当我们尝试在本地调试我们的云服务时,会在网页上显示异常,如下所示:

完全合格后路径太长.确保完整路径少于260个字符,目录名少于248个字符.

描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

异常详细信息:System.IO.FileLoadException:完全限定后路径太长.确保完整路径少于260个字符,目录名少于248个字符.

程序集加载跟踪:以下信息有助于确定无法加载程序集"Microsoft.Practices.EnterpriseLibrary.TransientFaultHandling.ServiceBus"的原因.

WRN: A partial bind occurs when only part of the assembly display name is provided.

从记录开始,似乎Microsoft.Practices.EnterpriseLibrary.TransientFaultHandling.ServiceBus.dll在上面的位置找不到,但实际上确实位于C:/AzureCloudService2/WebRole1/bin/,我已经多次检查过了.

几个信息:

• 我们只是通过Nuget安装软件包
• 我们还尝试过其他软件包,如TransientFaultHandling.Caching.etc,都有这样的问题.
• 有趣的是,它在工人角色中运作良好
