这种情况最近才开始突然发生。我尝试了在 Stack 和其他论坛上可以找到的所有解决方案，但到目前为止都没有奏效。
当我尝试开始调试 Azure 辅助角色时，这是我得到的：
调试窗口显示：The program '[2208] WaIISHost.exe' has exited with code 0 (0x0).
我在管理模式下运行 Visual Studio，将正确的项目设置为启动并使用 IIS Express 作为开发服务器。
我尝试使用相同的基础项目创建一个新的 Azure 辅助角色，但没有成功。系统事件日志没有任何信息。我尝试重新安装 VS2015 并单独安装 Azure SDK (v.2.7.1)，没有任何变化。当我查看计算模拟器时，在它消失之前它说：
[fabric] Role Instance: deployment27(250).Web.0
[fabric] Role state Unhealthy
[fabric] Role state Stopped
但是，我能够在解决方案中启动其他工作人员角色项目，这让我相信项目中一定有某些东西已经损坏，以某种方式与损坏的工作人员角色相关联。在这个阶段我没有想法，所以非常感谢任何帮助。
