How to call an async method from a getter or setter?

Question

What'd be the most elegant way to call an async method from a getter or setter in C#? Here's some pseudo-code to help explain myself. ``` async Task<IEnumerable> MyAsyncMethod() { return await DoSomethingAsync(); } public IEnumerable MyList { get { //call MyAsyncMethod() here } } ```

Accepted Answer

I really needed the call to originate from the get method, due to my decoupled architecture. So I came up with the following implementation.

Usage: Title is in a ViewModel or an object you could statically declare as a page resource. Bind to it and the value will get populated without blocking the UI, when getTitle() returns.

```
string _Title;
public string Title
{
    get
    {
        if (_Title == null)
        {   
            Deployment.Current.Dispatcher.InvokeAsync(async () => { Title = await getTitle(); });
        }
        return _Title;
    }
    set
    {
        if (value != _Title)
        {
            _Title = value;
            RaisePropertyChanged("Title");
        }
    }
}
```
