Hololens应用尝试与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在WCF Web服务上执行调用。我们的应用程序生成并部署OK，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.

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

我们尝试使用System.ServiceModel.dll的不同变体，它们位于“ C：\ Program Files（x86）\ Reference Assemblies \ Microsoft \ Framework.NETFramework”和“ C：\ Program Files \ Unity \ Editor \ Data \”中，没运气。不确定此错误是如何开始的，因为我们的应用程序过去可以正常工作。

客户电话代码

#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）

该服务运行正常，如下所示

Answer 1

关于使用哪个问题，位于Assets \ Plugins \ WSA \ x86 \ System.ServiceModel.dll的插件是正确的。

部署到设备是否显示相同的行为？另外，可以共享正在生成此错误的特定Unity版本吗？

我使用上面的代码做了一个测试UWP应用程序，以部署到HoloLens设备上，并且无法重现报告。因此，需要有关Unity版本的更多详细信息以提供帮助。
