DKNet

Convert FluentResults to HTTP results

Part of DKNet.AspCore.Extensions. Use the public Response overloads for handler results and hand-written endpoints:

using DKNet.AspCore.Extensions.Responses;
using FluentResults;
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.MapGet("/ok", () => Result.Ok("value").Response());
app.MapGet("/bad", () => Result.Fail("Refused").Response());
await app.RunAsync();

Input	isCreated	Output
Valued success, non-null	false	JSON value, 200.
Valued success, null	false	Empty 200.
Valued success	true	201 with literal location / and value.
IResultBase success	false / true	Empty 200 / 201.
Either failure	either	Problem response, normally 400; 404 if any error is NotFoundError.

Failure output resolves optional host ErrorResponseOptions when the result executes. The standard body has title: Error, status name in type, trace ID and a list of ErrorItem under errors. The internal problem builder is not a public bypass. See one error-response setting.

⚠️ Gotchas & limits

• Null input throws ArgumentNullException.
• The generic created-response location is /; it does not infer the new resource URL.
• Retired overloads accepting ErrorResponseOptions directly and the old public ToProblemDetails conversion path are not current APIs.
