WaitAny / WhenAny

The document implies that WaitAny needs to be wrapped in a try/catch. This is an error.

Code example:

var t = Task.Run(() => (1 == 1) ? throw new Exception(“good exception”) : 2);
var r = Task.WaitAny(new Task<int>[] { t }).Unwrap(); // no exception thrown
try
{
var i = r.Result;
Console.WriteLine(“all is well”);
}
catch (AggregateException ae)
{
var fe = ae.Flatten();
foreach (var e in fe.InnerExceptions)
Console.WriteLine($”Exception: {e.Message}”);
}
