For a test of the new nuget packages of MUnique.OpenMU.Network.Packets I wrote a small demo client.

You can find the source code here: https://github.com/sven-n/MuConsoleTestClient

It encapsulates most of the packet creation and parsing for you, so you don't have to mess around with bits and bytes yourself. Recently, I also added some automatically generated extension methods to make sending packets easier than ever.

Have fun :)
