常に400 Bad Request有効なリクエストを取得します。多分いくつかのヒント?これを非常にひどく修正する必要があります。

コントローラ

public class MyController : ApiController
{
    public IEnumerable<string> GetAll(string language)
    {
        return new [] {"a", "b", "c"};
    }
}

リクエスト

    $.ajax({
        type: "POST",
        url: "http://localhost:5378/Api/MyController/GetAll",
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        data: { "language": language },
        cache: false,
        complete: function (xhr) {
            console.output(xhr.status.toString());
        }
    });

WebApiConfig

public static void Register(HttpConfiguration config)
{
    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

    var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml");
    config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType);
}
