Post action in ASP.NET MVC always receives null

I have read a lot of questions regarding similar issues, but none of them seems to work for me.

I am receiving null for the movie object in the post action method.

This is my controller:

public class MovieController : Controller
{
    [Route("movies/all")]
    [HttpGet] 
    public ActionResult All()
    {
        List<string> movies = new List<string>();
        movies.Add("Some Movie");
        movies.Add("Diamond Team");

        //Get movies
        return Ok(movies);
    }

    [Route("movies/post")]
    [HttpPost] 
    public ActionResult Post([FromBody] Movie movie)
    {
        Console.WriteLine(movie);
        List<string> movies = new List<string>();
        movies.Add(movie.title);

        //Get movies
        return Ok(movies);
    }

    public ActionResult Index()
    {
        return View();
    }
}

This is the Movies class:

public class Movie
{  
    public string title { get; set; }
    public float rating { get; set; }
    public int year { get; set; }

    public Movie(string title,float rating, int year)
    {
        this.title = title;
        this.rating = rating;
        this.year = year;
    }

    public Movie()
    {

    }
}

This is the post request (using postman), I have tried either application/json and application/json; charset=utf-8 as the Content-Type but in both cases I have received null for the movie object:

{
    "title":"Some Movie",
    "rating":"1.87",
    "year":"2011"
}

Postman screenshots: Body

Headers

How can I fix this?

Please try to change your request JSON to this:

{
    "title":"Some Movie",
    "rating":1.87,
    "year":2011
 }

Your model must first be serialized and then passed to data in ajax call. this is one sample, You have to change the model according to your needs....

$("#btnPost").click(function() {  
        var employee = new Object();  
        employee.Name = $('#txtName').val();  
        employee.Address = $('#txtDesignation').val();  
        employee.Location = $('#txtLocation').val();  
        if (employee != null) {  
            $.ajax({  
                type: "POST",  
                url: "/JQueryAjaxCall/AjaxPostCall",  
                data: JSON.stringify(employee),  
                contentType: "application/json; charset=utf-8",  
                dataType: "json",  
                success: function(response) {  
                    if (response != null) {  
                        alert("Name : " + response.Name + ", Designation : " + response.Designation + ", Location :" + response.Location);  
                    } else {  
                        alert("Something went wrong");  
                    }  
                },  
                failure: function(response) {  
                    alert(response.responseText);  
                },  
                error: function(response) {  
                    alert(response.responseText);  
                }  
            });  
        }  
    });
