What Makes StepWise Special?

StepWise stands out by combining the power of C# with a simple, declarative approach to defining workflows. It automatically handles dependency resolution and parallel execution, making it perfect for scenarios where you need to coordinate multiple tasks efficiently.

How It Works

Here's a simple example that demonstrates StepWise's elegance. Let's say you're building a dinner preparation workflow:

// PrepareDinner.cs
public class PrepareDinner
{
    [Step]
    public async Task<string> ChopVegetables(string[] vegetables)
    {
        await Task.Delay(3000);
        return $"Chopped {string.Join(", ", vegetables)}";
    }

    [Step]
    public async Task<string> BoilWater()
    {
        await Task.Delay(2000);
        return "Boiled water";
    }

    [Step]
    [DependOn(nameof(ChopVegetables))]
    [DependOn(nameof(BoilWater))]
    public async Task<string> ServeDinner(
        [FromStep(nameof(ChopVegetables))] string[] vegetables,
        [FromStep(nameof(BoilWater))] string water)
    {
        return "Dinner ready!";
    }
}

The magic happens through simple attributes:

• [Step] marks methods as workflow steps
• [DependOn] defines dependencies between steps
• [FromStep] passes outputs from one step to another

This creates the following workflow in browser
