Not able to use inside Worker template

1. When running with RunTargetsAndExit

 protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                Target("default", () => System.Console.WriteLine("Hello, world!"));
                RunTargetsAndExit(decimal);
                _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
                await Task.Delay(1000, stoppingToken);
            }
        }

It runs first time but stops the application and gets stuck on

Waiting for the host to be disposed. Ensure all 'IHost' instances are wrapped in 'using' blocks.

2. When running with RunTargetsWithoutExiting

 protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                Target("default", () => System.Console.WriteLine("Hello, world!"));
                RunTargetsWithoutExiting(default);
                _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
                await Task.Delay(1000, stoppingToken);
            }
        }

It runs first time but gets stuck on

@iAmBipinPaul the problem is that this line, when executed a second time, throws an exception:

Target("default", () => System.Console.WriteLine("Hello, world!"));

This can be seen when setting VS to break when CLR exceptions are thrown:

I guess something in Microsoft.Hosting.Extensions is swallowing the exception.

Anyway, I believe we’ve determined that Bullseye is behaving as expected, so on that basis I’m closing the issue.

Thanks @iAmBipinPaul, I’ll take a look ASAP.
