Network programming is a complex and difficult task, so it's not surprising that many developers are looking for C# Networking libraries to help them with this task. While working with network protocols such as TCP/IP, UDP or HTTP, there are a lot of details that are hard to get right. Luckily, there are some excellent open-source C# libraries available that can make your life easier when you're working with these protocols.
DotNetty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Protobuf-net is a .NET library that allows serialization and deserialization of structured data into Protocol Buffers format. The project includes both a library (for serializing objects) as well as a command line tool (for generating code from schema definition files). They all provide support for multiple platforms, easy to use and have good documentation. Build enhanced networking configurations, protocols and performance optimizations in C# using these 23 libraries:
