.NET Inter-Process Communication: Named Pipes, .NET Remoting, or WCF – Which is Best?

Comparison of .NET inter-process communication solutions

When choosing an inter-process communication method in a .NET environment, be sure to evaluate the suitability of different options. Two potential methods include named pipes and .NET Remoting. However, upon closer inspection, a more comprehensive and powerful solution emerged: Windows Communication Foundation (WCF).

WCF is ideal for inter-process communication because it supports multiple transport mechanisms, including named pipes. This flexibility allows WCF to adapt seamlessly to different communication needs. Additionally, WCF is fully configuration-based, simplifying its implementation and management.

In terms of performance, WCF and .NET Remoting show comparable results. Testing shows that the difference in client latency is negligible, so their performance is relatively indistinguishable. However, WCF's server throughput is significantly higher, highlighting its efficiency in handling high-volume communications.

Given these advantages, WCF is highly recommended as the preferred solution for inter-process communication in .NET applications. Its versatility, ease of configuration and superior performance make it the best solution for scalable and robust communication scenarios.
