.Net Core WebAPI , Unable to post data with POSTMAN , error - 415 Unsupported MediaType

Question

I am testing my first .net Core WebAPI with Postman

unknown media type error is occurring.

What am I missing?

This is my posting object

public class Country
{
    [Key]
    public int CountryID { get; set; }
    public string CountryName { get; set; }
    public string CountryShortName { get; set; }
    public string Description { get; set; }
}

This is the webapi controller

[HttpPost]
public async Task<IActionResult> PostCountry([FromBody] Country country)
{
    if (!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }

    _context.Country.Add(country);
    try
    {
        await _context.SaveChangesAsync();
    }
    catch (DbUpdateException)
    {
        if (CountryExists(country.CountryID))
        {
            return new StatusCodeResult(StatusCodes.Status409Conflict);
        }
        else
        {
            throw;
        }
    }

    return CreatedAtAction("GetCountry", new { id = country.CountryID }, country);
}

You're not sending the Content-Type header. Choose JSON (application/json) in the dropdown near the mouse pointer on your first screenshot:
