Can constructors be async?

Question

I have a project where I\'m trying to populate some data in a constructor:

public class ViewModel
{
    public ObservableCollection Data { get;          


        

Answer 1

if you make constructor asynchronous, after creating an object, you may fall into problems like null values instead of instance objects. For instance;

MyClass instance = new MyClass();
instance.Foo(); // null exception here

That's why they don't allow this i guess.
