Web Api not binding to model

I'm trying to post a JSON object to a Web Api URL and it's not binding to the model.

This seems to be the same problem: ASP.Net Web Api not binding model on POST

I tried everything that they did and it still doesn't work. The one difference you may notice is that I'm not using the DataContract attributes, but I don't believe they should be required, and didn't make any difference when I tried them.

public class MyModel
{
    public int Id { get; set; }
}

Public class MyController : ApiController
{
    public int Save(MyModel myModel)
    {
        // myModel is always null
        return 0;
    }
 }

Fiddler setup

It could be an encoding issue. I changed my encoding and model binding is done succesfully.

client.Encoding = Encoding.UTF8;

You appear to be missing [HttpPost] attribute from your controller method. It appears in the above case this is actually not strictly required, perhaps this is only needed when posting primitives?

Also just as a note I would use a more REST based syntax if you are using WebApi for example use methods Get, Post, Put ect on your controller rather than named methods

EDIT:

You also have one other really subtle issue with your post. A header line cant end with a ; so Content-Type: application/json; charset=utf-8; should be Content-Type: application/json; charset=utf-8
