ASP.NET Core 10 Performance and Observability: Build Fast, Scalable Web APIs with OpenTelemetry, Caching, Profiling, Load Testing, and Production Diagnostics (The Practical ASP.NET Core Series)

Build ASP.NET Core APIs that are not only fast, but measurable, scalable, and ready for real production workloads.

ASP.NET Core 10 Performance and Observability is a practical guide to understanding how modern .NET applications behave under load, finding real bottlenecks, and using evidence to improve performance without relying on guesswork.

Using the production-oriented WorkBoard API, you will learn how to establish performance baselines, measure latency and throughput, create structured production logs, instrument applications with OpenTelemetry, and use metrics and distributed tracing to investigate problems across application and dependency boundaries.

You will also learn how to:

• Optimize ASP.NET Core request performance and EF Core/SQL Server queries
• Implement output, application, and distributed Redis caching
• Diagnose CPU, memory, garbage collection, and allocation problems
• Profile .NET applications using practical runtime diagnostic tools
• Design realistic load, stress, and capacity tests
• Build useful dashboards, alerts, and SLO-oriented production signals
• Detect regressions and troubleshoot real production incidents

Rather than teaching isolated optimization tricks, this book follows one core principle: measure first, optimize second, and prove the result.

Ideal for ASP.NET Core and C# developers who want to build faster, more observable, and production-ready .NET 10 Web APIs.
