How to add (not replace) the content of a DumpContainer in LINQPad

Question

I have a DumpContainer to which I'd like to add content dynamically. I know I can set the Content property to a new object but that gets rid of the previous content.

How can I add instead of replace?

Thanks for your help.

A couple more options:

If you want the items displayed vertically, but not in a table, use Util.VerticalRun inside a DumpContainer:

var content = new List<object>();
var dc = new DumpContainer (Util.VerticalRun (content)).Dump();

content.Add ("some text");
dc.Refresh();

content.Add (new Uri ("http://www.linqpad.net"));
dc.Refresh();

If the items are generated asynchronously, use an asynchronous stream (C# 8):

async Task Main()
{
    // LINQPad dumps IAsyncEnumerables in the same way as IObservables:
    RangeAsync (0, 10).Dump();
}

public static async IAsyncEnumerable<int> RangeAsync (int start, int count)
{
    for (int i = start; i < start + count; i++)
    {
        await Task.Delay (100);
        yield return i;
    }
}
