This post is part two of the series: Behind the scenes of minimal APIs. The author explains how the RequestDelegateFactory.InferMetadata() method works by inferring metadata from the delegate. The RequestDelegateFactory is responsible for creating a function that matches the RequestDelegate signature based on the provided delegate. As part of creating this method, the RequestDelegateFactory needs to analyze the provided delegate to determine the parameter types and return types the handler uses. The post provides examples of simple and complex minimal APIs and explains how they are handled by the RequestDelegateFactory. This post is a great resource for developers who want to dive deeper into the architecture of minimal APIs in .NET 7 and ASP.NET Core.
