asp.net-mvc - 网站未在 Azure 本地运行

Question

编辑:以管理员身份运行 Visual Studio 可以解决以下问题，但有人可以解释为什么我需要以管理员身份运行才能在 Azure 模拟器中运行网站吗？

我们正在将网站迁移到 Windows Azure，我已经创建了一个云服务并将网站添加为 Web 角色，当我尝试在调试中启动云服务项目时，它不会启动，并且在输出显示:

The program '[12396] WaIISHost.exe' has exited with code 0 (0x0).

左下角写着“操作已取消”。我似乎找不到发生这种情况的任何原因，如果我创建一个空白的 asp.net mvc 网站，它工作正常，所以我们的应用程序中一定有某些东西导致它像这样爆炸，有人知道如何做吗去追踪这个问题吗？

我只花了一秒钟时间查看模拟器输出，但它说:

[fabric] Role Instance: deployment24(29).xxx.Web.0
[fabric] Role state Busy
[fabric] Role state Unhealthy
[fabric] Role state Stopped

我在 waHostBootstrapper.log 中找到了以下条目

Answer 1

模拟器需要管理员权限才能执行多项任务。它需要控制 IIS，需要(经常)打开 1024 以下的端口，并且需要对工作进程具有控制权限。由于 Visual Studio 正在生成并控制它，这意味着 Visual Studio 也需要这些权限。

现在有一个“Express Emulator”选项可以缓解这一问题，但每个角色仅限一个实例，并且必须允许 IIS 使用随机高端口。有关在 Express 模拟器模式下运行的说明，请访问 http://msdn.microsoft.com/en-us/library/azure/dn339018.aspx .
