A simple .NET WPF application that can be used to establish TCP (raw) or WebSocket connections and exchange text messages for testing/debugging purposes.

• Supports TCP connections with a dual-mode socket (IPv6 and IPv4) and optionally using TLS
• Supports WebSocket connections (sending text messages and receiving text or binary messages)
• Supports half-closing the socket (send channel) before fully closing it
• Binary messages are encoded/decoded using a specified encoding like Windows-1252 (1 character per byte) or UTF-8
