FastPcapng

Small, hopefully fast, library with various utilities to handle pcapng file in .NET

Classes that might interest you:

1. MemoryPcapng - Store and modify a pcapng file structe in memory (no disk operation)
2. WiresharkPipeSender - Provides a quick way to "send" (or "export") a pcapng in memory (e.g. in MemoryPcapng or byte array) to wireshark over a named pipe
3. WeakPcapngFileHandle - Lazy pcapng file accessor. Avoid all disk operations until they are absolutely required.
