Look at EEIP Library. They have a C# and Java library for Ethernet/IP communication. They even offer some videos on YouTube on how to use it. But be aware, that some of this free libraries have some rough edges or bugs with them. Personally, I would use Modbus or another PLC before using Ethernet/IP along with a PC.

Look at AdvancedHMI. It is an HMI/SCADA Visual Studio toolkit with AB drivers. You can do most HMI stuff without writing code, but you can also use VB or C# for advanced tasks.

There is an open-source project called libplctag which has a few .NET wrappers, some of which are on nuget: https://www.nuget.org/packages/libplctag/, https://www.nuget.org/packages/PlcTag.Net/

Full disclosure: I'm one of the authors of the first wrapper.
