IIS Express routing is not working properly in Visual Sudio 2019

Question

I'm using Visual Studio 2019, and when I run the solution by IIS Express and send a request to my methods with postman, it returns a 404 status code . But when I run my solution using dotnet command in PowerShell, the app works properly and returns an OK response .

I think my code is correct because it works correctly when I run it with dotnet command , but I couldn't find a way to fix this problem.

I tried to change the SSL port in launchSettings.json , I tried to send request using both http and https, but none of them worked. Is there any problem with IIS Express or Visual Studio or what?

• Here is my launchSettings.json

    "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:6321/docs",
      "sslPort": 44444
    }

• This is my controller class

    [Route("api/[controller]")]
    public class ContentManagerController : Controller
    {
        [HttpPost]
        [Route("add")]
        public ContentManagerResponse AddSlider([FromBody]RequestClass request)
        {
            //some code
        }
    }

The routes are http://localhost:6321/api/ContentManager/add and https://localhost:44444/api/ContentManager/add

您的特定情况的解决方案是更改launchSettings.json的基本 URL。

"applicationUrl": "http://localhost:6321/"
