在我写这个问题的时候终于弄明白了！以为我还是会把它贴在盒子里帮助其他人。

问题：

我正在将我的 Windows 服务从 .NET Framework 4.x 升级到 .NET 5.0，它使用 Hangfire 在 .NET 中自动执行计划任务，其中一项任务是与 SAP 中的 Web 服务通信。

其中一个自动化作业使用来自 SAP I 的 SOAP 服务，但不能在 .NET 5.0 或 .NET Core 3.1 中使用它，但我可以在 .NET Framework 中使用它

我们正在使用很多定制的 SAP 服务。然而，这是最简单的一个。这是 WSDL（确实删除了绑定 URL 和身份属性）：

关于在.NET 5.0 中使用此 SOAP 的方法有什么想法吗？我的意思是最坏的情况，我们将其移至 OData，但理想情况下希望稍后再解决。

我尝试使用 WCF 服务引用添加它，但出现以下错误：

The optional WSDL extension element 'Policy' from namespace 'http://schemas.xmlsoap.org/ws/2004/09/policy' was not handled.
XPath: //wsdl:definitions[@targetNamespace='urn:sap-com:document:sap:soap:functions:mc-style']/wsdl:portType[@name='Z_DATA_FEEDS']/wsdl:operation[@name='ZOrderStatus']
The optional WSDL extension element 'Policy' from namespace 'http://schemas.xmlsoap.org/ws/2004/09/policy' was not handled.
XPath: //wsdl:definitions[@targetNamespace='urn:sap-com:document:sap:soap:functions:mc-style']/wsdl:portType[@name='Z_DATA_FEEDS']

这在项目中添加了一个 System.ServiceModel 的程序集，但抱怨 .NET 版本因此被编译为不同的框架。

【参考方案1】：

答案：

右键单击连接的服务，然后单击添加单击 Microsoft WCF Web 服务参考提供程序输入您的 URI 和任何选项，然后单击下一步/完成删除System.ServiveModel，因为它与.NET 5.0 不兼容

Install Package System.ServiceModel.Http
Install-Package System.ServiceModel.Primitives

对于我的服务类型，它是基本身份验证：

var basicHttpBinding = new BasicHttpBinding();
basicHttpBinding.MaxBufferSize = int.MaxValue;
basicHttpBinding.ReaderQuotas = System.Xml.XmlDictionaryReaderQuotas.Max;
basicHttpBinding.MaxReceivedMessageSize = int.MaxValue;
basicHttpBinding.AllowCookies = true;
basicHttpBinding.OpenTimeout = TimeSpan.FromMinutes(15);
basicHttpBinding.ReceiveTimeout = TimeSpan.FromMinutes(15);
basicHttpBinding.SendTimeout = TimeSpan.FromMinutes(15);

basicHttpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
basicHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

var endpoint = new EndpointAddress("## Enter your URL ##");

using (var client = new Analytics.ZWS_ANALYTICSClient(basicHttpBinding, endpoint))

    client.ClientCredentials.UserName.UserName = "## Your username ##"
    client.ClientCredentials.UserName.Password = "## Your password ##";

    // Call your web service method here

希望这能帮助遇到与我类似情况的人。
