我有一个带有 WCF 的 ASP.NET Core MVC 项目。我使用 IIS 将 WCF 发布到远程服务器，并通过以下方式使用客户端：
右键单击“连接服务”> 管理连接服务> 添加新服务引用
我从 .svc 页面粘贴了 WSDL 的链接。我设置的唯一自定义设置是选中“生成同步操作”并单击“完成”。当我尝试初始化 WCF 客户端时，出现以下错误：
'BillingSVCClient' does not contain a constructor that takes 0 arguments
这是我目前的代码：

我习惯在旧的 ASP.NET MVC 项目上以这种方式初始化 WCF，但 ASP.NET Core MVC 似乎以不同的方式工作。任何帮助，将不胜感激。谢谢！
将代码添加到 Reference.cs
public BillingSVCClient() :
base(BillingSVCClient.GetDefaultBinding(), BillingSVCClient.GetDefaultEndpointAddress())
{
this.Endpoint.Name = endpointConfiguration.ToString();
ConfigureEndpoint(this.Endpoint, this.ClientCredentials);
}
