Getting Started

Configure Workflow Service

public class WorkflowContext: EternityContext {

   public WorkflowContext(IServiceProvider services):
        base(new EternityAzureStorage(("ET", "azure storage connection string...")), 
            services, new EternityClock()) {
   }
}

// register this as background service
public class WorkflowBackgroundService : BackgroundService {
    private readonly WorkflowContext workflowContext;
    private readonly TelemetryClient telemetryClient;

    public WorkflowBackgroundService(WorkflowContext workflowContext, TelemetryClient telemetryClient)
    {
        this.workflowContext = workflowContext;
        this.telemetryClient = telemetryClient;
    }

    protected async override Task ExecuteAsync(CancellationToken stoppingToken) {
        while (!stoppingToken.IsCancellationRequested) {
            try {
                await workflowService.ProcessMessagesAsync(cancellationToken: stoppingToken);
            } catch (Exception ex) {
                telemetryClient.TrackException(ex);
            }
        }
    }
}

Register Service Scope

To enable Microsoft.DependencyInjection.Extensions Scope, add following in configure method.

services.AddEternityServiceScope();

This will make every activity execute in separate service scope, you can inject scoped services in Activities.

Create new workflow

// create new workflow and execute now
var id = await SignupWorkflow.CreateAsync(context, "[email protected]");

// raise an event...
await context.RaiseEventAsync(id, SignupWorkflow.Verify, verificationCode);
