Async Await with custom type C#

I have a model:

public class News
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Body { get; set; }
    public ObservableCollection<Comment> Comments { get; set; }
}

public class Comment
{
    public int CommentId {get;set;}
    public string CommentTitle{get;set;}
    public string CommentBody{get;set;}
}


public class APIData()
{

    public async Task<News> myNews()
    {
    var result = new News()
    /// GET xmlDATA

    var objComments = new ObservableCollection<Comment>();
    foreach(x in xmlData)
    {
        var objComment = new Comment();
    ////////////
        objComments.Add(objComment);
    }
    result.Comments = objComments;
    return result;
}

when I try to access it using api.myNews().Comments; I get error said ;

System.Threading.Tasks.Task does not contain a definition for Comments and no extension method accept first argument of type System.Threading.Tasks.Task could be found.

Please let me know. about this issue.

The method will return at Task which does not contain a property named Comments.

You need to await the Task:

var news = await api.myNews();
var comments = news.Comments;

If the method context is not async then use the Result.

var newsTask = api.myNews();
var comments = news.Result.Comments;
