iOS上的WCF TypeInitializationException错误

Question

我有一个跨平台的表单应用程序，在PCL中运行以下WCF代码没有问题，但在iOS上它会抛出TypeInitializationException错误。查看传入的参数，queryDevices参数显示为＆＃34; System.TypeInitializationException：System.Data.Services.Client.TypeSystem＆＃39; System.Data.Services.Client.TypeSystem＆＃39;的类型初始值设定项。抛出异常。＆＃34;

    IR_context = new IdentityServices.identityrelationships_dbEntities(svcUri);

    DataServiceQuery<IdentityServices.Device> queryDevices = (DataServiceQuery<IdentityServices.Device>)(from device in IR_context.Devices where device.MAC == DeviceID select device);

    try
    {
        // Begin query execution, supplying a method to handle the response 
        // and the original query object to maintain state in the callback.
        queryDevices.BeginExecute(OnDeviceQueryComplete, queryDevices);
    }

如何启用初始化？

您似乎需要在VS中将iOS项目的iOS Build Linker行为设置为“Off”以启用正确的链接。
