我有一个来自.NET Framework 4.8的WCF客户端，我需要将其移植到.NET Core，因为使用旧的客户端在升级基础项目后会给出PlatformNotSupportedException。
客户端是从WSDL文件生成的，在VS中将其添加为Connected Service可以很好地更新Reference.cs客户端，主要更改是GeneratedCodeAttribute被设置为"Microsoft.Tools.ServiceModel.Svcutil", "2.1.0"而不是"System.ServiceModel", "4.0.0.0"（在将dotnet-svcutil安装到项目中之后）。它还安装了这两个包，我相信在较新的.NET版本中是contains the CoreWCF client functionality：

• System.ServiceModel.Http（6.0.0）
• System.ServiceModel.Security（6.0.0）

我有一个集成，它正在创建一个生成的客户端，然后调用一个端点：

public string GetArticle(string articleNumber, string goal)
{
    using var client = CreateArtikelClient();
    return client.getArticle(articleNumber, goal);
}

private ArtikelPortTypeClient CreateArtikelClient()
{
    var client = new ArtikelPortTypeClient(ArtikelPortTypeClient.EndpointConfiguration.ArtikelPort);
    client.ClientCredentials.UserName.UserName = _integrationConfiguration.UserName;
    client.ClientCredentials.UserName.Password = _integrationConfiguration.Password;
    return client;
}

字符串
客户端创建得很好，但是调用getArticle会导致以下异常：

System.ServiceModel.Security.MessageSecurityException
  HResult=0x80131500
  Message=The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="Login please"'.

因此，以这种方式设置用户名和密码似乎不再足够，尽管它在.NET Framework中工作正常。我已经看到其他关于CoreWCF的帖子，其中凭据以这种方式设置，所以我不知道我错过了什么？
