在 Azure WebRole 中与 IIS 相同的端口上托管基于 TCP 的 WCF 服务（通过 Windows 激活服务）

Question

在与 IIS 相同的端口上使用基于 TCP 的 WCF 时，应如何配置 Azure Webrole？

本地解决方案通常会使用 WAS 激活，但这通常涉及在 HTTP 端口等上设置权限。在 Windows Azure 中，此接口不容易使用。

Answer 1

在 Azure WebRole 中托管 WCF 服务的最佳方法是使用 Windows 激活服务 (WAS ）。通常，当您想要在同一端口（80 或 443）上提供 Web 内容 (HTTP) 和某些基于 TCP 的 WCF 服务时，需要这样做。

下面是一个 PowerShell 脚本，它将启用 TCPPortSharing 服务并适当配置 IIS。虽然这适用于 Azure，但只需稍加修改，您也可以将其用于本地 Windows 2008 R2 服务器。
