iOS TypeInitializationException 错误上的 WCF

Question

我有一个跨平台表单应用程序，它在 PCL 中运行以下 WCF 代码没有问题，但在 iOS 上它会引发 TypeInitializationException 错误。查看传入的参数，queryDevices 参数显示为“System.TypeInitializationException: The type initializer for 'System.Data.Services.Client.TypeSystem' throw an exception.”

    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？

看来您需要在 VS 中将 iOS 项目的 iOS Build Linker Behavior 设置为“关闭”才能启用正确的链接。
