As Crowcoder said. You should register MediaTypeFormatter. Here simple arctile how do that provides to do what you want.

But simpler is choose another way to work with incoming data. As application/json. Create simple Dto class like:

public class TestDataDto
{
    public string Id { get; set; }
}

And change argument type of your Post method:

// POST api/values
public void Post([FromBody]TestDataDto value)
{

}

Then code of your core client should be like this:

static void Main(string[] args)
{
    using (HttpClient httpClient = new HttpClient())
    {
        var someData = JsonConvert.SerializeObject(new { Id = "test" });
        var content = new StringContent(someData, System.Text.Encoding.UTF8, "application/json");

        var result = httpClient.PostAsync("http://localhost:55878/api/values", content).Result;
        if (result.IsSuccessStatusCode)
        {
            Console.WriteLine("All is fine");
        }
        else
        {
            Console.WriteLine($"Something was wrong. HttpStatus: {result.StatusCode}");
        }
    }

    Console.ReadKey();
}
