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

I'm trying to implement a property that'll use the Sqlite await inside it:

public int ID {
        get
        {
            if (_id != null)
            {
                return _id;
            }
            if (string.IsNullOrEmpty(ImageName))
            {
                return -1;
            }
            var query = CurrentConnection.Table<Image>().Where(i => i.ImageName == ImageName);
            var result = await query.ToListAsync();
            ...other code

However, since a property is not set to await(tried that, doesn't work), I can't use await inside a property.

Any way to get around this besides using a method instead of a property?

No - there's no such thing as an async property. Even if you could declare an async property, it would have to be declared as having a return value of Task<int> rather than int... otherwise what would you want to return when you hit an await expression?

I would strongly suggest a GetIdAsync method here, assuming you definitely want async behaviour.
