Support for no-server/host?

[VictorioBerra]

We have a console app compiled to an exe that runs every night just a single time. Its executed by some fancy task runner.

I want to use the fluent API of workflow-core, the step classes, the input/outputs, the ease of failure handling, rollback, parallel running.

But, I don't want the polling system or persistence.

Proposed API:

public static void Main(string[] args)
{
    IServiceProvider serviceProvider = ConfigureServices();

    // Execute workflow without registering and starting a host
    var host = serviceProvider.GetService<IWorkflowHost>();
    host.ExecuteWorkflow<HelloWorldWorkflow>()
}

public class MyWorkflow : IWorkflow
{
    public void Build(IWorkflowBuilder<MyData> builder)
    {    
        builder
            .StartWith<CreateCustomer>()
            .Then<PushToSalesforce>()
                .OnError(WorkflowErrorHandling.Retry, TimeSpan.FromMinutes(10))
            .Then<PushToERP>()
                .OnError(WorkflowErrorHandling.Retry, TimeSpan.FromMinutes(10));
    }
}
