如何为IOTHUB提供运输处理程序？

Question

我正在尝试连接到Iothub以配备设备。

我在一个大风WASM应用程序中。

我已经创建了安全提供商对称密钥：

SecurityProvider symmetricKeyProvider = new SecurityProviderSymmetricKey(parameters.DeviceId, parameters.DeviceSymmetricKey, null);

但是我要调用的下一行：

            ProvisioningTransportHandler mqttTransportHandler = new ProvisioningTransportHandlerMqtt(TransportFallbackType.TcpOnly);

我已经尝试了TCPonly后备，并且没有传递任何后备，并且都给了我同样的错误。例外是：

Error provisioning device: The type initializer for 'Microsoft.Azure.Devices.Provisioning.Client.Transport.ProvisioningTransportHandlerMqtt' threw an exception.
System.TypeInitializationException: The type initializer for 'Microsoft.Azure.Devices.Provisioning.Client.Transport.ProvisioningTransportHandlerMqtt' threw an exception.
 ---> System.InvalidOperationException: failed to create a child event loop.
 ---> System.PlatformNotSupportedException: Operation is not supported on this platform.
