在与IIS相同的端口上使用基于TCP的WCF时,应该如何配置Azure Webrole?
本地解决方案通常使用WAS激活,但是这通常涉及在HTTP端口等上设置权限。在Windows Azure中,此接口不容易使用。
解决方法
在Azure WebRole中承载WCF服务的最佳方法是使用Windows激活服务(WAS)。当您要在同一端口(80或443)上提供Web内容(HTTP)和某些基于TCP的WCF服务时,通常需要这样做。
这是一个PowerShell脚本,它将启用TCPPortSharing服务并适当地配置IIS。尽管此方法适用于Azure,但稍作修改后,您也可以将其用于本地Windows 2008 R2服务器。
