C# 从.Net Core 2.0调用SOAP api时出错

我们使用.NETCore2.0版本调用外部SOAP服务

相关调用方法为：

public async void Login(/*string username, string password*/)
{
    try
    {
        OBASEMDMClient client = new OBASEMDMClient();
        var loginCredential = new LoginCredential
        {
            UserNameOrEMail = "username",
            Password = "password"
        };
        var response = await client.LoginAsync(loginCredential);
    }
    catch (Exception e )
    {
        throw e;
    }
}

我们得到的答复是：

接收对的HTTP响应时出错http:///OBASEMDM.svc. 这可能是由于服务端点绑定未使用HTTP协议造成的。 这也可能是由于服务器中止了HTTP请求上下文（可能是由于服务关闭）

但是当我们使用SOAPUI来校准服务时，我们得到了成功的响应：

SOAPUI请求：

这是相关服务的WSDL架构：

我们如何使用.Net Core 2.0调用此服务？

async void

在事件处理程序之外是fire and forget

这可能就是上下文可能超出范围并中止的原因

应该重构该方法以返回

Task

public async Task LoginAsync(string username, string password) {
    try {
        OBASEMDMClient client = new OBASEMDMClient();
        var loginCredential = new LoginCredential {
            UserNameOrEMail = username,
            Password = password
        };

        var response = await client.LoginAsync(loginCredential);

        //...
    } catch (Exception e ) {
        throw e;
    }
}
