vs alljoyn Studio-生成的消费者失败了

Question

是否有人在使用vs alljoyn studio生成的消费者代码中有任何经验丰富的system.io.filenotfoundexception？

我正在尝试使用VS Alljoyn Studio扩展名创建AllJoyn启用的UWP应用程序。通过提供的工具，我能够生成Alljoyn样板代码库，用于从我的样本内置XML创建生产者和消费者。我能够创建生产者UWP，将其部署到运行Windows 10 IoT Core的RPI 3设备，然后使用IoT Explorer连接到它。使用Alljoyn Explorer，我能够更改网络上运行的生产者的状态。当我从Alljoyn Explorer中执行setDesiretemperature方法时，我将获得成功，并且更改反映在接口上的deSiredTemperperature属性上。PS-这是我的第一个Alljoyn应用程序。

这是我的消费者代码，它在此通话中引发了试图实例化消费者的例外：

_consumer =等待温度feptureconsumer.fromidasync（args.id）;

 /// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainPage : Page
{
    private TemperatureConsumer _consumer;
    private DeviceWatcher _deviceWatcher;
    public MainPage()
    {
        this.InitializeComponent();

        _deviceWatcher = AllJoynBusAttachment.GetWatcher(new List<string> { TemperatureConsumer.InterfaceName });
        _deviceWatcher.Added += Watcher_Added;
        _deviceWatcher.Start();
    }
    private async void _deviceWatcher_Added(DeviceWatcher sender, DeviceInformation args)
    {
        // throws System.IO.FileNotFoundException;
        _consumer = await TemperatureConsumer.FromIdAsync(args.Id);
    }
    private void Button_Click(object sender, RoutedEventArgs e)
    {
        _deviceWatcher = AllJoynBusAttachment.GetWatcher(new List<string>() { TemperatureConsumer.InterfaceName });
        _deviceWatcher.Added += _deviceWatcher_Added;
        _deviceWatcher.Start();
    }
}

这是我的生产者代码，它有效：

/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainPage : Page, ITemperatureService
{
    private AllJoynBusAttachment _allJoynBusAttachment;
    private TemperatureProducer _temperatureProducer;
    private double _temperature;
    public double Temperature
    {
        get { return _temperature; }
        set
        {
            _temperatureProducer?.EmitDesiredTemperatureChanged();
            _temperature = value;
        }
    }

    public MainPage()
    {
        this.InitializeComponent();
        _allJoynBusAttachment = new AllJoynBusAttachment();
        _allJoynBusAttachment.StateChanged += _allJoynBusAttachment_StateChanged;
        _allJoynBusAttachment.CredentialsRequested += _allJoynBusAttachment_CredentialsRequested;
        _temperatureProducer = new TemperatureProducer(_allJoynBusAttachment);
        _temperatureProducer.Service = this;
        _temperatureProducer.Start();
    }
    public IAsyncOperation<TemperatureGetDesiredTemperatureResult> GetDesiredTemperatureAsync(AllJoynMessageInfo info)
    {
        return Task.Factory.StartNew(() => TemperatureGetDesiredTemperatureResult.CreateSuccessResult(Temperature)).AsAsyncOperation();
    }
    public IAsyncOperation<TemperatureSetDesireTemperatureResult> SetDesireTemperatureAsync(AllJoynMessageInfo info, double interfaceMemberDesiredValue)
    {
        return Task.Factory.StartNew(() =>
        {
            Temperature = interfaceMemberDesiredValue;
            return TemperatureSetDesireTemperatureResult.CreateSuccessResult();
        }).AsAsyncOperation();
    }
    private void _allJoynBusAttachment_CredentialsRequested(AllJoynBusAttachment sender, AllJoynCredentialsRequestedEventArgs args)
    {
        // throw new NotImplementedException();
    }
    private void _allJoynBusAttachment_StateChanged(AllJoynBusAttachment sender, AllJoynBusAttachmentStateChangedEventArgs args)
    {
        //  throw new NotImplementedException();
    }
}

内省XML：

<?xml version="1.0" encoding="utf-8"?>
<node>
<interface name="com.inlynk.Sensor.Temperature">
<method name="SetDesireTemperature">
  <annotation name="org.alljoyn.Bus.Secure" value="true" />
  <arg name="desiredValue" type="d" direction="in"></arg>
</method>
<property name="DesiredTemperature" type="d" access="read">
   <annotation name="org.freedesktop.DBus.Property.EmitsChangedSignal"   value="true"/>
</property>
</interface>
</node>

Answer 1

所以，我找到了自己问题的答案。如果使用最新版本的Alljoyn Studio，我所需要做的就是让我的消费者应用程序目标构建14393。如果我更改了金色的最小目标和最大目标。请参阅此处

1. 右键单击该项目
2. 选择属性
3. 在应用程序菜单屏幕设置为目标和最大为14393
上

希望这会有所帮助。
