Aspire with .NET 10

Build modern cloud-native ASP.NET Core applications with Aspire and .NET 10.

Aspire with .NET 10 is a practical guide to designing, running, observing, and preparing distributed ASP.NET Core applications for production. Rather than building a disposable demo, this book continues the WorkBoard application from The Practical ASP.NET Core Series and shows how Aspire can be introduced into an existing application without replacing its core architecture.

You will learn how to use the Aspire AppHost to model application services and infrastructure, manage SQL Server and Redis resources, configure service discovery, connect multiple .NET services, and use Service Defaults for health checks, resilience, and OpenTelemetry.

Through practical examples, you will also build background processing with a dedicated worker, diagnose distributed failures with logs and traces, manage configuration and secrets, work with containers, and understand the important distinction between Aspire development orchestration and real production hosting.

Inside, you will learn how to:

• Build an Aspire AppHost for an existing ASP.NET Core 10 application
• Model SQL Server, Redis, containers, and distributed resources
• Implement service discovery and resilient service-to-service communication
• Configure health checks, logs, metrics, and distributed tracing
• Add caching without making Redis the source of truth
• Build reliable background processing with a worker and SQL outbox
• Diagnose dependency failures using the Aspire Dashboard
• Manage configuration, parameters, secrets, and resource dependencies
• Prepare Aspire-based applications for containers and managed cloud services
• Design a practical production-ready distributed application architecture

If you already understand ASP.NET Core and want to move beyond single-process applications, Aspire with .NET 10 provides a practical path toward building distributed .NET systems that are easier to start, understand, observe, troubleshoot, and deploy.
