Working with configuration

To configure a driver extension, configuration files are used. These files must be located in the Files\Driver area of the project and have to be configured at assembly settings.

public Task InitializeAsync(ILogger logger, IValueCallback valueCallback, string configFilePath)
{
  _logger = logger;
  _valueCallback = valueCallback;

  var configurationBuilder = new ConfigurationBuilder()
      .AddJsonFile(configFilePath, optional: true);
  var configuration = configurationBuilder.Build();
  var serverAddress = configuration["MqttServerAddress"] ?? "localhost";

  return Task.CompletedTask;
}
