Converted AuthClient to work with .net core

[MarkOates71]

I've rewritten the AuthClient class to work with .net core but run into an issue with the cert, the problem I have is I'm seeing a betfair response of CERT_AUTH_REQUIRED

I'm newish to c#/ .net core so any help would be appreciated, and once working i'll post the code here

thanks Mark

I have just done the same thing, where did you get stuck? The below returns a session id so from there you should be good.

Make sure you've uploaded your .pfx to betfair and allowed cert auth.

I fixed this the day after posting but didn't get chance to post my solution which is more aligned to the original code, see below, I did already have cert uploaded to Betfair. I ended up replacing the method getWebRequestHandlerWithCert with one of my own (which references HttpClientHandler instead of WebRequestHandler) called GetHttpClient

Original Code private WebRequestHandler getWebRequestHandlerWithCert (string certFilename) { var cert = new X509Certificate2(certFilename, "");

        var clientHandler = new WebRequestHandler();
        clientHandler.ClientCertificates.Add(cert);
        return clientHandler;
    }

Changed to.....

private HttpClientHandler GetHttpClient(X509Certificate2 certData) {

        //specify to use TLS 1.2 as default connection
        System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

        var clientHandler = new HttpClientHandler();

        clientHandler.ClientCertificateOptions = ClientCertificateOption.Manual;
        clientHandler.SslProtocols = SslProtocols.Tls12;

        X509Certificate2 newCert = new X509Certificate2(certData);
        clientHandler.ClientCertificates.Add(newCert);
        return clientHandler;

    }

Let me know if you try this out Mark
