KrakenOrderbookOptions error messages

The websocket connection works based on events. So when you're calling SubscribeToTickerUpdates you connect to a stream and when data is received on that stream you get an update. To handle the update you'll have to pass an update handler to the subscribe method. This is what the data => {} bit is.
Between the {} you'll have to handle the data. What to do with it is obviously up to you, but having a console application this will simply write the price of the latest tick to the console:

client.SubscribeToTickerUpdates("XBT/EUR", data => { 
      Console.WriteLine(data.Market + " last trade price: " + data.Data.LastTrade.Price);
});

The initial error cannot convert from 'int' to 'Kraken.Net.Interfaces.IKrakenSocketClient' is because the kraken order book doesn't need the same parameters as the binance order book you copied from the examples. I'll add to the examples that different order books might need slightly different parameters.

The basic kraken order book only needs a limit specified like this:
new KrakenSymbolOrderBook("XBT/USD", 100);
The socket client you can pass in the options is used to combine multiple order book on the same socket connection.

The second error you ran into is refering to the limit parameter, a limit of 1 is not supported. I know a limit of 100 is supported, but I'm not sure what all other possible values might be. Also note that the market you pass ('XXBTZEUR') is not a valid websocket market. The KrakenSymbolOrderBook uses a websocket connection, and the websocket needs different market names than the Rest API uses.. (thanks kraken)
To get the correct websocket name of a market you can use the GetMarkets call on the KrakenClient and use the WebsocketName of the market you're interested in. For Bitcoin / Euro that would be XBT/EUR:
new KrakenSymbolOrderBook("XBT/EUR", 100);

By changing the KrakenSymbolOrderBook to:
KrakenSymbolOrderBook orderBook = new KrakenSymbolOrderBook("XBT/EUR", 100);

It works like a charm, thank you for your help.

I have never worked with WebSockets before, and you are super helpfull. :)

var subResult = client.SubscribeToTickerUpdates("XBT/EUR", data => { });
subResult contains Succes = true;

But where does the Kraken.Net.Objects.KrakenStreamTick go ?
I don't know how to get it, and after i get it, how do i get an updated value at the next tick ?
Sorry for posting a non issue, but maybe this can be added to the manual.

Thanks(and sorry)

Thank you, this is exactly what i needed to know!
I did it like this (as an example)

var subResult = client.SubscribeToTickerUpdates("XBT/EUR", data => Ticker(data));
 
      static void Ticker(Kraken.Net.Objects.Socket.KrakenSocketEvent<Kraken.Net.Objects.KrakenStreamTick> tick)
        {
            var a = tick.Data;
            var bid = a.BestBids;
            var ask = a.BestAsks;
        }

Yup that's fine.
(You could shorthand it by writing client.SubscribeToTickerUpdates("XBT/EUR", Ticker);, which is the same)
