How to use FromForm attribute in ASP.NET Web API 5.2.3

Question

I have created a brand new project in VS 2017 - by using the Web API template. But I am not able to use [FromForm] attribute in the controller action method.

Here some lines from package.config:

<package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net461" />
<package id="Microsoft.AspNet.Razor" version="3.2.3" targetFramework="net461" />
<package id="Microsoft.AspNet.Web.Optimization" version="1.1.3" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi" version="5.2.3" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net461" />

Is the [FromForm] available in Web API version 5.2.3?

If not then how to read FormData values?

Code:

[HttpPost]
[Route("v1/users/register")]
public void RegisterUser(FormDataCollection formData)
{
    var fName = formData["firsName"]; // formData is NULL
}

Postman request:

FromForm attribute intends to asp core. You cannot use it in .net web api project. — Oleg Levin

Yes, you can also try do it with model as parameter without any model binding attributes. — Oleg Levin

You can get form data from

HttpContext.Current.Request.Form: key and value.

Files: HttpContext.Request.Form.Files.

Post action must be without input or can be with HttpRequest parameter, like:

RegisterUser(HttpRequest request) and request.Form....
