I have this query: 

```
public static class myClass
{ 

    list<something> myList = new list<something>();

    public void PopulateList()
    {
        var myQuery = from a in db.something
              where a.someproperty == somevar
              select a;   

        myList  = myQuery.Tolist();
    }
}

```

How can i do to make this query async?
