Question

我所有的WCF通信都开始遇到错误。当我尝试在Visual Studio中添加/连接到IIS部署的WCF服务时，出现此异常：

There was an error downloading 'http://localhost/f-service/ServiceHost/v1/BillService.svc?singleWsdl'.
The underlying connection was closed: An unexpected error occurred on a receive.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
An existing connection was forcibly closed by the remote host
Metadata contains a reference that cannot be resolved: 'http://localhost/f-service/ServiceHost/v1/BillService.svc?singleWsdl'.
Content Type application/soap+xml; charset=utf-8 was not supported by service
http://localhost/f-service/ServiceHost/v1/BillService.svc?singleWsdl。客户端和服务绑定可能不匹配。远程服务器返回错误：（415）由于内容类型为'application / soap + xml，因此无法处理该消息； charset = utf-8' 不是预期的类型'text / xml; charset = utf-8'。如果服务是在当前解决方案中定义的，请尝试构建解决方案并再次添加服务引用。

该服务仅在几天前运行。现在，如果我访问该页面，则会得到基本页面（注意：另一个遭受saem问题的服务的屏幕截图）：

但是我对?wsdl或?singleWsdl链接没有任何回应：

我无法为该服务创建客户端。有人有任何想法吗？只有Windows 10 Insider Preview更新为最新版本，并且没有软件包更新。

更新

我观察到：这是一个本地问题。如果将相同的源代码构建在不同的PC上，则可以正确运行/提供服务
切换到IIS Express也可以

WCF服务错误元数据包含无法解析的引用
