```CSharp
new ServerSentEventsTransport()
{
    ConnectionTimeout = TimeSpan.Zero,
    ReconnectDelay = TimeSpan.Zero
},
new LongPollingTransport()
{
    ErrorDelay = TimeSpan.Zero
}
```

This would allow Delay in OnConnected to be much shorter. You may be able to get away without using `FallbackToLongPollingConnection` at all since it will fail nearly instantly.
