Feature/Add Quartz.NET Integration for Background Job Scheduling by alnuaimicoder · Pull Request #1263 · CommunityToolkit/Aspire

alnuaimicoder · 2026-04-02T12:25:31Z

Closes #1259

Overview

This PR adds a production-ready integration for background job scheduling using Quartz.NET in .NET Aspire applications.

.NET Aspire currently lacks native support for background job scheduling. Developers must manually integrate Quartz.NET or Hangfire, configure persistence, set up observability, and implement idempotency themselves. This integration solves that problem by providing an Aspire-native solution.

What's Included

Three Packages

CommunityToolkit.Aspire.Hosting.Quartz (Hosting Integration)
- Resource pattern for Quartz.NET
- Automatic database configuration (PostgreSQL, SQL Server)
- Health checks integration
- OpenTelemetry metrics
- Automatic schema migrations
CommunityToolkit.Aspire.Quartz (Client Integration)
- IBackgroundJobClient for dynamic job scheduling
- Idempotency support (prevent duplicate execution)
- Retry policies with exponential/linear backoff
- OpenTelemetry distributed tracing
- Full Quartz.NET power (cron expressions, triggers, listeners)
CommunityToolkit.Aspire.Quartz.Abstractions (Core Abstractions)
- Core interfaces: IJob, IBackgroundJobClient
- Shared types: JobOptions, RetryPolicy, JobContext

Key Features

Aspire-native patterns - Built for Aspire from the ground up
Production features - Idempotency, OpenTelemetry, health checks out of the box
Multi-database support - PostgreSQL and SQL Server with auto-migrations
Full Quartz.NET power - No feature hiding, complete access to Quartz.NET APIs
All-in-one architecture - No separate worker needed, jobs run in your API service
Type-safe API - Strong typing with generics for job parameters

Usage Example

AppHost

var builder = DistributedApplication.CreateBuilder(args);

var postgres = builder.AddPostgres("postgres")
    .AddDatabase("quartzdb");

builder.AddProject<Projects.ApiService>("api")
    .WithReference(postgres);

builder.Build().Run();

API Service

var builder = WebApplication.CreateBuilder(args);

builder.AddServiceDefaults();
builder.Services.AddQuartzClient(builder.Configuration.GetConnectionString("quartzdb"));

var app = builder.Build();

app.MapPost("/jobs/enqueue", async (IBackgroundJobClient jobClient) =>
{
    var jobId = await jobClient.EnqueueAsync<SendEmailJob>(
        new { email = "user@example.com" },
        new JobOptions { IdempotencyKey = "email-123" });

    return Results.Ok(new { jobId });
});

app.Run();

Job Definition

public class SendEmailJob : IJob
{
    private readonly ILogger<SendEmailJob> _logger;

    public SendEmailJob(ILogger<SendEmailJob> logger) => _logger = logger;

    public async Task Execute(IJobExecutionContext context)
    {
        var email = context.JobDetail.JobDataMap.GetString("email");
        _logger.LogInformation("Sending email to {Email}", email);
        await Task.Delay(1000);
        _logger.LogInformation("Email sent successfully!");
    }
}

NuGet: https://www.nuget.org/packages/AspireQuartz (v1.0.1)
GitHub: https://github.com/alnuaimicoder/aspire-hosting-quartz

Other Information

Why This Integration Matters

Background job scheduling is a fundamental requirement for most production applications. Currently, .NET Aspire developers must:

Manually integrate Quartz.NET or Hangfire
Configure database persistence themselves
Set up observability from scratch
Implement idempotency and retry logic
Handle health checks separately

This integration makes background jobs a first-class citizen in Aspire, just like databases, caches, and messaging.

Design Decisions

Three-package structure: Separates abstractions, client, and hosting for clean dependency management
Aspire.Hosting namespace: Extension methods in Aspire.Hosting for discoverability
No wrapper abstraction: Full access to Quartz.NET APIs - we enhance, not hide
All-in-one architecture: Jobs run in API service, no separate worker needed (simpler deployment)
Multi-database support: PostgreSQL and SQL Server (MySQL and SQLite can be added later)

Maintenance Commitment

I'm committed to:

Long-term maintenance of this integration
Responding promptly to issues and feedback
Keeping up with Aspire and Quartz.NET updates
Adding features based on community needs

Database Migration

The integration includes automatic database migration:

On application startup, QuartzMigrationService checks if Quartz tables exist
If not, executes SQL script to create all required tables
Tables are stored in the configured database (PostgreSQL or SQL Server)
No manual migration files needed

Production Features

Idempotency: Prevent duplicate job execution using IdempotencyKey
OpenTelemetry: Full distributed tracing and metrics
Health Checks: Built-in health check support
Retry Policies: Exponential and linear backoff strategies
Type Safety: Strong typing with generics

#1263 I've addressed the feedback and pushed the requested changes. Please take another look when you have time.

Quick initial pass - we aren't using the PublicAPI.* files anymore and they should be removed.

aaronpowell · 2026-05-25T05:55:21Z

    <PackageVersion Include="Microsoft.NET.StringTools" Version="17.11.48" />
    <PackageVersion Include="Microsoft.Build.Locator" Version="1.10.12" />
+    <PackageVersion Include="Npgsql" Version="10.0.2" />
+    <PackageVersion Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="10.0.1" />


This dependency doesn't appear to be used and as a result it triggers a full test suite run of the solution (if we can't tell where something is used it triggers everything).

If it's needed, ensure there's a csproj that references it, otherwise it can be removed.
