Here are some of the famous C# Networking Libraries. C# Networking Libraries use cases include Building a Chat Application, Building an Online Multiplayer Game, building a Networked File Sharing Application, building a Networked Database Application, and Building a Networked Streaming Media Application.
C# networking libraries are the collection of classes and functions used to develop C# programming language network applications. These libraries provide functionality such as networking protocols, data transfer, encryption, and data storage. Examples of C# networking libraries include the .NET Framework Network Classes, System.Net, and OpenNETCF.
Let us have a look at these libraries in detail below.
