Discussion
17 comments analyzed.
Competitors mentioned: IRC clients, Rider IDE, Avalonia (cross-platform framework)
Concerns raised: TCP message handling fails for messages >1500 bytes without proper framing, No message delimiter or size prefix causes random production failures, Buffer overflow risk with 4096 byte fixed buffers, Code doesn't properly handle TCP stream fragmentation, Violates Microsoft C# conventions on class separation
Feature requests: Handle messages larger than 4096 bytes, Implement message size prefix or delimiter protocol, Support for messages longer than buffer size
