Dependencies

Framework references

• Microsoft.AspNetCore.App — the ASP.NET Core shared framework.

Project references

• AlmightyShogun.AspNet.Core — provides the shared error response shape.

Startup Registration

AddAspNetValidation registers the rule cache, filters, and exception handler. UseAspNetValidation adds the middleware, and has overloads for minimal API endpoints and route groups.

WARNING

AddMessageLocalization and AddHttpErrorResponseWriter must also be called. Without them, validation messages resolve to their raw keys such as validation.required.
