It's probably me, but when I load the parser I get the following error:

For reference, the relevanty part of my proxy is

#load "parser.csx"
using static System.Console;
using static CANAPE.Cli.ConsoleUtils;

var template = new FixedProxyTemplate();
// Local port of 4444, destination 192.068.56.101:12345
template.LocalPort = 4444;
template.Host = "192.168.56.101";
template.Port = 12345;
template.AddLayer<Parser>();

(which worked before adding the parser) and the parser is:

using CANAPE.Net.Layers;
using System.IO;

class Parser : DataParserNetworkLayer
{
    protected override bool NegotiateProtocol(Stream serverStream, Stream clientStream)
    {
        var client = new DataReader(clientStream);
        var server = new DataWriter(serverStream);
        // Read magic from client and write it to server.
        uint magic = client.ReadUInt32();
        Console.WriteLine("Magic: {0:X}", magic);
        server.WriteUInt32(magic);
        // Return true to signal negotiation was successful.
        return true;
    }
}

I'd be much obliged if you could let me know where I'm going wrong. Thanks, Dave

Edit: hang on... I tried to go back to the non-parser proxy and I'm getting the same error. Methinks I've messed up somewhere...

Edit 2: I've gone back to the original proxy script and am getting the same error. It looks environmental.

The story for getting the application framework 1.1 on Core 2.0 isn't great, especially on Linux. As Canape Core should run quite happily when built for 2.0 we should update the projects so that it builds and runs without any requirements on 1.1.

Packages that require license acceptance require a License URL to be provided. Did you have one you wanted to provided?

Toggling the requirement works around this build issue.

Tls proxy is not working with netcore 3.0 properly, I think. Because magic byte is coming all wrong. https://i.imgur.com/aYpfpy5.jpg
