IndexOutOfRangeException when parse packet about packetnet HOT 8 CLOSED

Sorry, the packetdotnet was old, i recompiled the new sourcecode and now it's working

from packetnet.

I still get this exception with the Nuget version. It only happens on TCPv6 packets. Version 0.13.0

Will you be updating the Nuget package?

Have you tested this with the latest 0.19 version?

from packetnet.

@stricq I think you may be using someone elses package, this is the official package: https://www.nuget.org/packages/PacketDotNet/

from packetnet.

@chmorgan I'm quite certain I'm using your nuget package. I just updated to the version you just released (0.19.1) and I'm still getting the exception. Here is my line of code:

if (packet.Extract(typeof(TcpPacket)) is TcpPacket tcpPacket) {

Here is the full project: https://github.com/stricq/TcpMonitor

It is the Extract method where the exception happens.
