	using System.Buffers;
	using System.Net.WebSockets;

	var builder = WebApplication.CreateBuilder(args);
	var app = builder.Build();

	app.MapGet("/ws", async (HttpContext context) =>
	{
	var ws = await context.WebSockets.AcceptWebSocketAsync();
	var incomingMessages = new MessagePipe<WebSocketMessageType>();
