I am getting an error 0000 Error {000}: [00000003] Invalid mime type "binary": does not contain '/'

var client = new RSocketClient(new WebSocketTransport("ws://127.0.0.1:7000/quotes"), new RSocketOptions() { 
    InitialRequestSize = 3,
    DataMimeType = "application/x-binary",
    MetadataMimeType = "application/x-binary"
});

await client.ConnectAsync();

what's the mime type format to use for rsocket request stream of various binary object types? The client shows that there is a mime type.

A wireshark capture shows the error that appears to come from port 7000 the Java Server saying that the Net client has produced the wrong mime type

it is a bug in RSocket-.Net. you shell pass your RSocketOptions derictly into ConnectAsync instead of passing them into the RSocketClient constructor:

var client = new RSocketClient(new WebSocketTransport("ws://127.0.0.1:7000/quotes"));

await client.ConnectAsync(new RSocketOptions() { 
    InitialRequestSize = 3,
    DataMimeType = "application/x-binary",
    MetadataMimeType = "application/x-binary"
});
