调用 ProvisioningDeviceClient 的 RegisterAsync 时抛出异常

Question

我有一个下面的方法，用

C#

写的

 public async Task<DeviceRegistrationResult> RegisterDevice(ProvisioningDeviceClient provClient)
    {
        DeviceRegistrationResult registrationResult = null;
        try
        {
            registrationResult = await provClient.RegisterAsync().ConfigureAwait(false);

            if (registrationResult.Status != ProvisioningRegistrationStatusType.Assigned) {
               

            }
           
        }

        catch (Exception ex)
        {
           
        }
        return registrationResult;
    }

这个方法是这样调用的

   var deviceRegistrationResult = await _dpsDeviceClient.RegisterDevice(provClient);

我低于错误

System.MissingMethodException：'找不到方法：'System.Threading.Tasks.Task`1 Microsoft.Azure.Devices.Provisioning.Client.ProvisioningDeviceClient.RegisterAsync()'。'

我正在使用 Microsoft.Azure.Devices.Provisioning.Client 库的 1.5.2 版。

我还尝试将 Microsoft.Azure.Devices.Provisioning.Client 升级到 1.19.2，这次它没有显示异常，但我的应用程序崩溃了。奇怪的是，在

Catch

部分没有发现异常。

以下代码用于创建

ProvisioningDeviceClient

 using (var transport = new ProvisioningTransportHandlerMqtt(TransportFallbackType.WebSocketOnly))
   {
   provClient = ProvisioningDeviceClient.Create(GlobalDeviceEndpoint, "MyIdScope",
                     security, transport);
   }

注意：出于安全目的，帖子中未提及 MyIdScope。
