To create an ASP.NET Core API controller in F#, generate the controller structure using established command-handler patterns, define request and response DTOs with validation, and implement domain error mapping.

The command-handler pattern for F# API controllers separates request handling logic into distinct command handlers, ensuring standardized controller structure, consistent authorization checks, and centralized domain error mapping.

Add custom JSON converters to an F# ASP.NET Core controller by implementing specific conversion logic for targeted data types, ensuring custom serialization patterns are consistently applied during request and response processing.

Yes, this approach supports built-in DTO validation for F# backend APIs by guiding the creation of Data Transfer Objects with integrated validation rules to ensure data integrity before command execution.

Map domain errors in an F# ASP.NET Core API by enforcing consistent error mapping patterns within the controller layer, translating backend domain failures into standardized HTTP responses.
