Example how to publish language at runtime, including schema, via messaging

public class PublishLanguageHandler : IRequestHandler<PublishLanguage>
    {
        private readonly IMessageBusPublisher _messageBusPublisher;
        private readonly ITopicRegistry _topicRegistry;
        private readonly IConfiguration _configuration;
        private readonly ISchemaResolver _schemaResolver;

        public async Task<Unit> Handle(PublishLanguage request, CancellationToken cancellationToken)
        {
            var baseEventType = typeof(INotification);

            var schemaDefinitions =
                _schemaResolver.GetSchemas(new[] { typeof(MyCommand).Assembly }, baseEventType, type => _topicRegistry.GetTopicForMessageType(type, false));

            var schemaDefinitionUpdated = _schemaResolver.BuildSchemaUpdatedEvent(schemaDefinitions, GetSourceId());
            await _messageBusPublisher.PublishAsync(schemaDefinitionUpdated, cancellationToken);

            return Unit.Value;
        }

        private string GetSourceId()
        {
            var source = _configuration.GetSection("Messaging")?["Source"];
            return source ?? "";
        }
