在Azure Web中與IIS（通過Windows激活服務）相同的端口上託管基於TCP的WCF服務角色

Question

在與IIS相同的端口上使用基於TCP的WCF時，應如何配置Azure Webrole？

內部部署解決方案通常會使用WAS激活，但這通常涉及對HTTP端口的設置權限等。在Windows Azure中，此接口不是現成的。

Answer 1

在Azure WebRole中託管WCF服務的最佳方式是使用Windows Activation Service (WAS)。通常，當您希望在同一端口（80或443）上提供Web內容（HTTP）和某些基於TCP的WCF服務時，需要使用此功能。

這是一個PowerShell腳本，它將啓用TCPPortSharing服務並適當地配置IIS。儘管這適用於Azure，但稍加修改即可將其用於內部部署Windows 2008 R2服務器。
