c# - 为什么/如何将自承载 WCF 服务迁移到 IIS7？

Question

我编写了一些 WCF 服务，出于开发和调试目的，我以自托管的方式运行这些服务。现在我已经启动了一个 Web 服务器，我正在考虑是否有任何理由将我的服务更改为在 IIS 7 下运行...如果是，如何？..

MSDN 有一篇文章探讨了不同的 WCF hosting楷模。这是关于自托管的内容:

The following are the advantages of self-hosting:

• Is easy to use: With only a few lines of code you have your service running.
• Is flexible: You can easily control the lifetime of your services through the Open() and Close() methods of ServiceHost.
• Is easy to debug: Debugging WCF services that are hosted in a self-hosted environment provides a familiar way of debugging, without having to attach to separate applications that activate your service.
• Is easy to deploy: In general, deploying simple Windows applications is as easy as xcopy. You don't need any complex deployment scenarios on server farms, and the like, to deploy a simple Windows application that serves as a WCF ServiceHost.
• Supports all bindings and transports: Self-hosting doesn't limit you to out-of-the-box bindings and transports whatsoever. On Windows XP and Windows Server 2003, IIS limits you to HTTP only.

The following are the disadvantages of self-hosting:

• Limited availability: The service is reachable only when the application is running.
• Limited features: Self-hosted applications have limited support for high availability, easy manageability, robustness, recoverability, versioning, and deployment scenarios. At least, out-of-the-box WCF doesn't provide these, so in a self-hosted scenario you have to implement these features yourself; IIS, for example, comes with several of these features by default.
