I have to use an .SVC WebService in my MVC project.我必须在我的 MVC 项目中使用.SVC WebService。 When I want to add the service through Add Service Reference , then I get the following error:当我想通过Add Service Reference 添加服务时，我收到以下错误：

There was an error downloading https://.............svc/ $metadata'.下载https://................svc/ $metadata' 时出错。 The request was aborted: Could not create SSL/TLS secure channel.请求被中止：无法创建 SSL/TLS 安全通道。

I tried generating my required classes to use the service with the following command in CMD:我尝试使用 CMD 中的以下命令生成所需的类以使用该服务：

svcutil.exe https://.............svc?wsdl svcutil.exe https://................svc?wsdl

But I get the following error message:但我收到以下错误消息：

Error: Cannot obtain Metadata from https://.............svc?wsdl错误：无法从https://................svc?wsdl获取元数据

How can I solve this problem?我怎么解决这个问题？

The aforementioned error mainly indicates that we should trust the server certificate before we download the service metadata.上述错误主要表明我们在下载服务元数据之前应该信任服务器证书。
As @rene mentioned.正如@rene 提到的。 After we have generated the client proxy class, we could instantiate the class to invoke the method like calling a local method.在我们生成客户端代理 class 之后，我们可以实例化 class 来调用方法，就像调用本地方法一样。
But we also could invoke the service by adding service reference, which is a built-in feature in VS.但是我们也可以通过添加服务引用来调用服务，这是 VS 的一个内置特性。
