CSharpFunctionalExtensions.Asp

ASP base controller for use with CSharpFunctionalExtensions

This library converts CSharpFunctionalExtensions.Result to HTTP errors but using the base controller CSharpFunctionalBase and calling the method MapToActionResult

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")))
             .Finally(authResult => MapToActionResult(authResult));

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
