IPC Implementation Options for Windows Applications in C# (.NET 2.0)

Interprocess communication (IPC) allows multiple processes to exchange data and coordinate their actions. For applications in Windows, C# (.NET 2.0) offers several robust and error-prone IPC methods to meet specific requirements.

Named Pipes

Named pipes provide a reliable and efficient way to communicate between processes in close proximity. With .NET 3.0 and above, the NetNamedPipeBinding class in WCF facilitates IPC on the same machine. The class provides a code-friendly API for both synchronous and asynchronous communication.

Remoting

Introduced in .NET 1.0, remoting is a legacy IPC framework that is no longer actively developed. It uses a TCP channel by default, providing straightforward implementation. However, it is recommended to use WCF for modern IPC requirements.

Win32 RPC with RpcLibrary

The csharptest-net RpcLibrary project wraps the Win32 RPC library, enabling IPC through Remote Procedure Calls (RPCs). This approach provides strong performance and security but may require a deeper understanding of RPC principles.

WM_COPYDATA

For simple IPC scenarios, the WM_COPYDATA message available in Win32 can be utilized. It allows processes to exchange structured data in small chunks. The API is straightforward but may be less convenient for more complex IPC tasks.

Custom Socket Protocol

Developing a custom socket protocol provides ultimate flexibility for specific requirements. However, it requires significant effort in designing and implementing a reliable and efficient communication layer.
