Request.CreateResponse in asp.net core

Below is my code (Partial code) and I want to migrate it into asp.net core.
My problem is “Request.CreateResponse” is not working in below code. I google it a lot but unable to find any solution. How can I solve it? Package Microsoft.AspNet.WebApi.Core is also not working.

    [HttpPost]
    public HttpResponseMessage AddBusinessUsersToBusinessUnit(MyObject request)
    {
        return Request.CreateResponse(HttpStatusCode.Unauthorized);
    }

Thanks in advance.

Method 1

Finally I make a solution. 🙂

[HttpPost]
public HttpResponseMessage AddBusinessUsersToBusinessUnit(MyObject request)
{
    return new HttpResponseMessage(HttpStatusCode.Unauthorized);
}

Method 2

If you just want to return a status code, the following is preferable

//Creates a StatusCodeResult object by specifying a statusCode.
//so controller method should return IActionResult 
return StatusCode(HttpStatusCode.Unauthorized)

See more in this SO answer

Method 3

Instead of returning Request.Create Response, Latest version allows to return Ok for 200 http status code & add a model on your response if you want to
Also Return IActionResult instead of HttpResponseMessage

public IActionResult Method()
{
  try
  {
     return Ok(new TokenResponseModel { Status = "ok", Message = "valid token" });
  }
}

Method 4

For Core 2.1+, return ActionResult or IActionResult instead of HttpResponseMessage. This gives you incredible flexibility. Below is the example that also returns content back.

[HttpPost]
public ActionResult<BusinessUsers> AddBusinessUsersToBusinessUnit(MyObject request)
{   var businessUsers = AddBusinessUsers(request);
    return Request.CreateResponse(HttpStatusCode.Unauthorized, businessUsers);
}

In Core 3.0, you must determine all possible return types with ProducesResponseType

Method 5

Try this out, below is sample HTTP get controller function

   using System;
   using System.Net.Http;
   using System.Net;
   using System.Web.Http;
   using System.Threading.Tasks;
   using Newtonsoft.Json;
   using Newtonsoft.Json.Linq;

    [HttpGet]
    public async Task<ActionResult<string>> GetItem()
    {
        try
        {
            var Item = null;
            return JsonConvert.SerializeObject(Item);
        }
        catch (Exception ex)
        {
            HttpRequestMessage request = new HttpRequestMessage();
            HttpResponseMessage response = request.CreateErrorResponse(HttpStatusCode.InternalServerError, ex.Message);
            throw new System.Web.Http.HttpResponseException(response);
        }
    }

Method 6

Try something like that

public async Task<IActionResult> Method()
{
  try
  {
     var content = someCollectionReturnedFromDatabase();
     return Ok(content);
  }
  catch(Exception ex)
  {
    _logger.LogWarning(ex.Message, ex);
    return BadRequest(ex.Message); // this can be something like notfound
  }
}
