即使我的云服务在azure RoleEnvironment上运行。IsAvailable为false。我的服务在IIS 8.5上运行，它在网络服务下运行。

知道我在这里做错了什么吗?当我远程进入并改变网络时也是如此。通过在IIS RoleEnvironment中添加空间来配置一点。IsAvailable被求值为true。

我也使用Azure 2.5版本

RoleEnvironment.IsAvailable在应用程序启动时设置为false

这是一个已知的错误，导致RoleEnvironment.IsAvailable总是在模拟器上返回false，请参阅https://connect.microsoft.com/VisualStudio/feedback/details/695609/roleenvironment-isavailable-is-useless-returns-true-when-invoked-by-code-not-hosted-in-azure-emulator了解更多信息。

你可以做如下的事情，直到这个错误被修复:

if ( RoleEnvironment.IsEmulator || RoleEnvironment.IsAvailable)
{
// Role is available
}

应该是

if ( RoleEnvironment.IsAvailable && RoleEnvironment.IsEmulated)
{
     // we are running the workerrole locally in debug 
}
