C# sample demonstrates the NDISAPI usage in several filtering scenarios. Available ion x86 and x64 configurations. AnyCPU configuration is not available due to the C++/CLI nature of ndisapi.net wrapper (see https://github.com/kevin-marshall/Managed.AnyCPU for the workaround). Projects references PacketDotNet (https://github.com/chmorgan/packetnet) for dumping network packets headers.
