Testing LLM Event Parsing in C# with Promptfoo
A developer demonstrates evaluating an LLM-powered event parser using Promptfoo, testing a C# app that extracts structured event data from casual messages. The project uses a shared prompt file to ensure consistency between runtime and evaluation. This approach addresses the challenge of validating LLM outputs that vary in format but remain semantically correct.

Practical guide for developers building LLM features, but the technique is standard prompt testing—nothing novel beyond the C# integration example.
