.Net sample CloudEvent

hi guys,

I created a sample .net application following the example below, which sends Strings to a topic

Apache Kafka and .NET - Getting Started Tutorial (confluent.io)

However, I am now trying to send CloudEvents but I am unable to find an example to refer to. Appreciate some help

 CloudEvent cloudEvent = new CloudEvent
                Id = "event-id",
                Type = "event-type",
                Source = new Uri("https://cloudevents.io/"),
                Time = DateTimeOffset.UtcNow,
                DataContentType = "application/json",
                Data = content

producer.Produce(topic, new Message<string, CloudEvent> { Key = user, Value = cloudEvent}

The above code is not even compiling.
