.NET 10 is the fastest runtime in history, but is your API utilizing it? Minimal APIs have matured from a "lightweight alternative" to the performance standard for cloud-native microservices.

This session explores advanced features of Minimal APIs in .NET 10, focusing on the new validation integration, NativeAOT (Ahead-of-Time compilation), and the Request Delegate Generator (RDG). We will perform live coding of a high-performance microservice, optimizing it step-by-step - from a standard implementation to a natively compiled, allocation-free beast.

We will cover:

Validation 2.0: Utilizing the new AddValidation method and source generators to secure inputs without reflection overhead.

NativeAOT: Trade-offs, "gotchas," and massive startup time gains for serverless deployments.

Observability: Leveraging new .NET 10 metrics and OpenTelemetry support to find bottlenecks.
