Describe the bug

I've just been testing upgrading a couple of projects from Aspire 13.0.2 -> 13.1.0

In both cases, I now get a startup error in AuxiliaryBackchannelService.
Never knowingly used this; looks to be something to do with MCP (neither project uses anything MCP related).

Doesn't seem to be breaking anything functional in my projects, but is throwing errors out at startup:

info: Aspire.Hosting.DistributedApplication[0] Aspire version: 13.1.0+8a4db1775c3fbae1c602022b636299cb04971fde info: Aspire.Hosting.DistributedApplication[0] Distributed application starting. info: Aspire.Hosting.DistributedApplication[0] Application host directory is: C:\..removed..\AppName.AppHost fail: Aspire.Hosting.Backchannel.AuxiliaryBackchannelService[0] Error in auxiliary backchannel service System.Net.Sockets.SocketException (10050): A socket operation encountered a dead network. at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, Boolean disconnectOnFailure, String callerName) at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Bind(EndPoint localEP) at Aspire.Hosting.Backchannel.AuxiliaryBackchannelService.ExecuteAsync(CancellationToken stoppingToken) in /_/src/Aspire.Hosting/Backchannel/AuxiliaryBackchannelService.cs:line 58

Everything then carries on, but given I know nothing of this specific component, I'm unclear what the implications are. In any case, it probably shouldn't be doing that...
