环境：Windows XP，Visual Studio 2010中，IIS 不安装。WCF服务，在WCF SVC主机的工作，不工作作为Windows服务
我已经开发了一个WCF服务作为WCFSvcHost托管时工作正常库;我可以连接到它，更新客户的服务参考，作品。
我无法承载它作为Windows服务，虽然。该服务安装好，我可以附加到它并打破我的代码。为了调试主机，我将代码移到了OnResume（）（OnStart什么都不做）。
这里是我的onResume（名称已更改为保护无辜者）：
protected override OnResume()
{
if (_selfHost == null)
{
_selfHost = new ServiceHost(typeof(MyService));
_selfHost.Open();
}
}
当通过Open（）方法步进，我得到以下异常：
System.InvalidOperationException was unhandled by user code
Message=The HttpGetEnabled property of ServiceMetadataBehavior is set to true and the HttpGetUrl property is a relative address, but there is no http base address. Either supply an http base address or set HttpGetUrl to an absolute address.

没有量改变我的配置文件似乎解决了这个问题：
<?xml version="1.0" encoding="utf-8"?>

作为一个测试，我试图设置httpG etEnabled为False，并删除MEX终结点，但只有移到别处的问题：错误信息消失并启动服务，但后来我的客户端不能调用服务：
System.ServiceModel.EndpointNotFoundException was caught
Message=There was no endpoint listening at http://localhost:8732/MyService/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

任何帮助吗？
你有没有尝试在控制台应用程序托管？不是为了替代服务，而只是为了确保它能够工作？ – 2012-02-20 22:45:59
另外 - 我会通过一个非常简单的例子来得到一个WCF服务作为一个Web服务来运行，看看这样做是否有助于你看到你在做什么不同。请参阅：http://msdn.microsoft.com/en-us/library/ms733069.aspx – 2012-02-20 22:48:00
特里：聪明的想法。我得到与Windows服务相同的错误。 – dlesage 2012-02-20 23:23:09
