Examples
Hello World: Console
The following is a simple Hello World workflow created as a console application. The workflow is created using C#.
using Elsa.Extensions;
using Elsa.Workflows.Core.Activities;
using Elsa.Workflows.Core.Services;
using Microsoft.Extensions.DependencyInjection;
// Setup service container.
var services = new ServiceCollection();
// Add Elsa services.
services.AddElsa();
// Build service container.
var serviceProvider = services.BuildServiceProvider();
// Create a workflow.
var workflow = new WriteLine("Hello World!");
// Resolve a workflow runner to run the workflow.
var workflowRunner = serviceProvider.GetRequiredService<IWorkflowRunner>();
// Run the workflow.
await workflowRunner.RunAsync(workflow);
Outputs:
Hello World!
