Accessing injected dependencies in executors

[mvp013]

I don''t seem to be able to find any information about executors and dependencies.
All the examples related to executor have very basic functionality, such as uppercase, reverse etc

If I need to access an injected service from within an executor how do I go about this?
I am assuming I am missing some fundamental aspect of executors here.

EDIT: I am aware I can just pass them during construction!

You've got it — constructor injection is the intended pattern. Executors are plain classes, so you pass dependencies through the constructor:

public class MyExecutor : Executor
{
    private readonly IMyService _service;

    public MyExecutor(string id, IMyService service) : base(id)
    {
        _service = service;
    }
}

When registering workflows with the hosting layer, the AddWorkflow factory delegate gives you access to IServiceProvider, so you can resolve services from DI there:

builder.AddWorkflow("myWorkflow", (sp, key) =>
{
    var myService = sp.GetRequiredService<IMyService>();
    var executor = new MyExecutor("my-executor", myService);
    return new WorkflowBuilder(executor).Build();
});

This is in HostApplicationBuilderWorkflowExtensions.AddWorkflow() if you want to look at the source.
