The following is a much simpler code that causes the same issue:

using System;
using System.Threading.Tasks;

public class Program
{
    public static async Task Main()
    {
        Console.WriteLine("TEST");
        await Task.Delay(500);
        Console.WriteLine("TEST2");
    }
}

Hello, I was simply trying code that works in Visual Studio to see if it worked online.

@karenpayneoregon , Yes, you're correct that there is a bug. I just provided a smaller code to be easier for the dotnet/try team to investigate it :)

Thank you :-)

It no longer blocks the page, but the continuation code after await simply doesn't get invoked, e.g.:
