Multiple processes are multi-threaded in parallel?

[hypnosis01]

public class AspSample : StepBody { private static readonly Logger log = LogManager.GetCurrentClassLogger(); private static volatile int _counter = 0;

public AspSample()
{
    log.Debug("AspSample init ...");
}

public override ExecutionResult Run(IStepExecutionContext context)
{
    if (_counter % 2 == 0) 
    {
        Thread.Sleep(2000);
    }
    log.Debug($"StepBody: {nameof(AspSample)}");
    AspSample._counter++;
    return ExecutionResult.Next();
}

}

var host = serviceProvider.GetService(); host.StartWorkflow("PTWorkFlow", 1, null); host.StartWorkflow("PTWorkFlow", 1, null); host.StartWorkflow("PTWorkFlow", 1, null); host.StartWorkflow("PTWorkFlow", 1, null);

Multiple process implementations were initiated。

Multiple processes are executed serially.......

How do I make each process instance execute in a separate thread?

Don't use Thread.Sleep, use Async and Task.Delay and it will work as expected. The problem is Thread.Sleep blocks the thread that enters the workflow execution preventing additional executions from starting.

That being said I think this behavior should not need this to work.
