c# - Hololens 应用程序尝试与 WCF Web 服务进行 HTTP 连接时缺少方法异常？

Question

我们正在尝试使用 System.ServiceModel.dll 对我们的 WCF Web 服务进行调用。我们的应用程序构建和部署正常，但在运行时会生成以下错误..

System.MissingMethodException: The method 'System.Void System.ServiceModel.BasicHttpBinding::.ctor()' has no implementation.

该应用程序使用位于 Assets/Plugins/WSA/x86/ 中的 System.ServiceModel.dll 构建，并配置为在 Hololens 平台 (WSAPlayer) 上使用，如下所示。如何解决缺少方法异常？

我们尝试使用“C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework”和“C:\Program Files\Unity\Editor\Data\”中可用的 System.ServiceModel.dll 的不同变体，但没有成功. 不确定这个错误是如何开始的，因为我们的应用程序过去可以毫无复杂地工作。

客户端调用代码

#if !UNITY_EDITOR
public static Service1Client client;
#endif

void Awake()
{
#if !UNITY_EDITOR
    client = new Service1Client(new BasicHttpBinding(),
        new EndpointAddress("http://myServer/myService/myService.Service1.svc"));

    ((BasicHttpBinding)client.Endpoint.Binding).MaxBufferSize = 200000000;
    ((BasicHttpBinding)client.Endpoint.Binding).SendTimeout = System.TimeSpan.FromMinutes(3);
    ((BasicHttpBinding)client.Endpoint.Binding).MaxReceivedMessageSize = 200000000;
#endif
}

MyServiceClient.cs（从命令行使用 Svcutil.exe 生成）

该服务运行良好，如下所示
