NuGet Package: Escendit.Extensions.Workflows

This NuGet package provides a streamlined integration with Temporal.io for .NET applications, offering simplified configuration and dependency injection setup for building robust, distributed workflow applications. It wraps Temporal's .NET SDK with opinionated defaults and convenient extension methods.

Key features:

• Simplified Temporal client and worker configuration
• Built-in dependency injection integration
• Pre-configured JSON serialization with System.Text.Json
• OpenTelemetry tracing support out of the box
• Worker versioning and deployment management
• Keyed service registration for multi-tenant scenarios
• Production-ready defaults for common use cases

Installation

To install this package, use the NuGet Package Manager Console:

shell PM> Install-Package Escendit.Extensions.Workflows

Or you can search for "Escendit.Extensions.Workflows" in the NuGet Package Manager UI and install it from there.

Usage

Basic Setup

Register Temporal services in your Program.cs or Startup.cs:

// Add Temporal hosted service with minimal configuration
builder
    .Services
    .AddTemporalHostedService("<task queue>")
    .ConfigureWorkerOptions(builder =>
    {
        builder
            .AddWorkflow<OrderWorkflow>()
            .AddActivity<CreateOrderActivity>()
            .AddActivity<ProcessOrderActivity>();
    });

Advanced Configuration

Configure Temporal with custom settings:

builder
    .Services
    .AddTemporalHostedService("<task queue>", "<target host>", "<namespace>", "<build id>")
    .ConfigureWorkerOptions(builder =>
    {
        builder
            .AddWorkflow<OrderWorkflow>()
            .AddActivity<CreateOrderActivity>()
            .AddActivity<ProcessOrderActivity>();
    });

Using Keyed Services

For multi-tenant applications or multiple Temporal connections:

// Register multiple Temporal clients
builder
    .Services
    .AddKeyedTemporalClient("<name>", "<target host?>", "<namespace?>");

builder
    .Services
    .AddKeyedTemporalClient("<name>", "<target host?>", "<namespace?>");

// Use in your services
public class OrderService
{
    private readonly ITemporalClient _clientA;
    private readonly ITemporalClient _clientB;

    public OrderService(
        [FromKeyedServices("<name 1>")] ITemporalClient clientA,
        [FromKeyedServices("<name 2>")] ITemporalClient clientB)
    {
        _clientA = clientA;
        _clientB = clientB;
    }
}

Configuration

Default Settings

The package uses the following defaults:

Setting	Default Value	Description
ClientTargetHost	localhost:7233	Temporal server address
ClientNamespace	default	Temporal namespace
UseWorkerVersioning	false	Enable worker versioning (true if buildId provided)
DataConverter	System.Text.Json	JSON serialization using System.Text.Json
Tracing	Enabled	OpenTelemetry tracing interceptors

Customizing Client Options

You can further customize the Temporal client after registration:

builder
    .Services
    .AddTemporalHostedService("<name>")
    .ConfigureClientOptions(options =>
    {
        options.RetryConfig = new RetryConfig { InitialInterval = TimeSpan.FromSeconds(1), MaximumInterval = TimeSpan.FromMinutes(1), BackoffCoefficient = 2.0, MaximumAttempts = 3 };
    });

Worker Versioning

Enable worker versioning for safe deployments:

builder
    .Services
    .AddTemporalHostedService( "<task queue>", buildId: Environment.GetEnvironmentVariable("BUILD_ID"))
    .ConfigureWorkerOptions(builder =>
    {
        builder
            .AddWorkflow<OrderWorkflow>()
            .AddActivity<CreateOrderActivity>()
            .AddActivity<ProcessOrderActivity>();
    });

Dependencies

This package depends on:

• Temporalio.Extensions.Hosting - Temporal .NET SDK hosting extensions
