Question

我正在尝试为我的网络服务更改架构。我需要制作一个WCF服务。我只想制作一个服务，然后在IIS或Windows服务中托管它。这是否可能，使这种WCF服务重用？我该怎么做呢？这种情况是我们的一些客户无权启动Windows服务，但可以在IIS中安装WCF。

提前谢谢。

Answer 1

WCF服务只是一个遵循WCF 托管接口的程序集，然后提供允许访问它的客户端接口。

在IIS，Windows服务，WinForm应用程序或控制台应用程序中，托管WCF服务同样。这真的没关系。

客户端界面保持不变，但接口的公开方式可能会因托管方案而异。例如，您可能会在IIS情况下使用一个http绑定，但可能会对Windows服务使用TCP绑定。这些绑定可以在配置文件中定义，因此代码不一定必须更改以适应以某种方式托管。

简而言之，创建WCF服务应该独立于最终托管的方式。但是，为了便于维护，我选择了一种或另一种 - Windows服务或IIS。

你可以让一个Windows服务托管WCF并公开它上面的所有端点..Http，TCP .. Windows服务比IIS更好，因为IIS本身就是一个进程，然后我们在它上面放置一个VD来托管我们的网站/ WCF。对于Windows服务，它将是一个只适用于WCF的专用线程。我正在共享Windows服务的app.config（详细信息已更改）显示我们如何托管WCF ...希望它有所帮助..
