ASP.NET: error - server error in application "/"

Question

I am working on an ASP.NET MVC project and every time I try to start my view Register.cshtml, I get this error:

Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly. 

Requested URL: /User/Register

I am trying to create a registration page with a code of the form:

  @{
        ViewBag.Title = "Register";
        Layout = "~/Views/Shared/_Layout.cshtml";
    }

<h2>Register</h2>

<form action='@Url.Action("Register", "Controller")'>

    <input type="hidden" name="FormType" value="A" />
    <input type="hidden" name="FormType" value="B" />
    <input type="text" name="Name" placeholder="enter your name" />
    <input type="text" name="Password" placeholder="enter your name" />
    <input type="radio" name="typeOfForm" class="radioBtn" value="A">Form A
    <input type="radio" name="typeOfForm" class="radioBtn" value="B">Form B
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
    <div style="display: none" id="formA" action="/actionA">
        <input type="text" name="City" placeholder="City" />  <input type="submit" value="Register Me!" />
    </div>

    <div style="display: none" id="formB" action="/actionB">
        <input type="text" name="Age" placeholder="Age" /><input type="submit" value="Register Me!" />
    </div></form>

<script>
    $('.radioBtn').click(function () {
        var formType = $(this).val();
        //alert(formType);
        if (formType == "A") {
            $('#FormA').show();
            $('#FormB').hide();
        } else {
            $('#FormB').show();
            $('#FormA').hide();
        }
    });</script>

with UserController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace BootstrapSite4.Controllers
{
    public class UserController : Controller
    {   [HttpGet]
        [HttpPost]
        // GET: User
        public ActionResult Register(char FormType, string name, string password)
        {
            Seller S = new Seller();
            DeliveryMan D = new DeliveryMan();
            if (FormType=='A')
                S.Name = name;
            else 
                D.Name = name;
            return View();}}}

I tried changing my RegisterRoutes, but still getting the same error. I think my mistake is only with location! just a brief description of the idea of ​​registration: I have types of users who fill out the registration form, and depending on what they have chosen (in the radio buttons), the rest of the form will appear on the same page so that they continue to register, then add it to the database data.

HttpGet Register UserController:

[HttpGet]
public ActionResult Register()
{
    return View();
