CSharpFunctionalExtensions.Asp

ToActionResult extension method converts Result<T, Error> from CsharpFunctionalExtensions to Asp.Net Core ActionResult.

Run the sample program to try it out.

Example:

   public ActionResult<AuthenticationResult> Register(RegisterRequest request) =>
        Domain.User.Create(request.firstName, request.lastName, request.email, request.password)
             .Bind(user => Result.Success<AuthenticationResult, ErrorList>(new AuthenticationResult(user, "token")))
             .ToActionResult(this);

If a validation failure occurs, it will return a response like

HTTP/1.1 400 Bad Request
Connection: close
Content-Type: application/problem+json; charset=utf-8
Date: Mon, 14 Nov 2022 20:29:19 GMT
