Hi @StendProg, in #692 @jl0pd commented about this method:

@jl0pd said we are not awaiting real operation, but only the creation of a task. By doing this users may begin to work data which is not yet updated properly. This solution was offered:

public async Task SetSourceAsync(T[] data)
{
    sourceArray = data ?? throw new ArgumentNullException("Data cannot be null");
    await Task.Run(() => UpdateTrees());
}

This makes sense to me, as UpdateTreesInBackground() is just Task.Run(() => { UpdateTrees(); }), but before making this change I wanted to double check and make sure it looks good to you too. @StendProg, what do you think?
