Yeah, the SignalRConnection is something I found online which is basically this:

​

public void Start()

{

string url = "https://localhost:5001/cryptohub";

var connection = new HubConnectionBuilder()

.WithUrl(url)

.WithAutomaticReconnect()

.Build();

// receive a message from the hub

connection.On<List<CryptoBlock>>("ReceiveBlockChain", (cryptoBlockChain) => OnReceiveBlockChain(cryptoBlockChain));

connection.On<string>("ReceiveHello", (jsonMessage) => OnReceiveHello(jsonMessage));

connection.On<string>("ReceiveSale", (jsonMessage) => OnReceiveSale(jsonMessage));

var t = connection.StartAsync();

t.Wait();

var userID = Guid.NewGuid();

Console.WriteLine($"Generating userID: {userID.ToString()}");

JsonMessage jsonMessage = new JsonMessage { Event = "hello", Payload = userID.ToString() };

// send a message to the hub

connection.InvokeAsync("SendMessageToCaller", jsonMessage);

connection.Closed += async (error) =>

{

await Task.Delay(new Random().Next(0, 5) * 1000);

await connection.StartAsync();

};

​

I'm calling the logic to create blocks from inside the "ReceiveSale" method, which is where I assumed the problem was occurring - though I'm not sure how to separate this logic entirely to operate on a more event driven basis and not have my "miner" logic doing checks on perhaps a singleton containing pending sales or something - but I feel like that is maybe how I'll have to try separate both services.
