I was making some tests, as soon as I use anything from the library I get that error, I made a blank app, added the dll, put the using argument, and then on the form load I put this line:
NetworkComms.AppendGlobalIncomingPacketHandler<string>("Message", PrintIncomingMessage);
Without it, there was no error, as soon as I put it, the io error appears.
I made a debug with the unmanaged code option activated, I get this that seems related to that error:
