How to Implement Minimal WCF Named Pipe Communication?

Minimal Example of WCF Named Pipe Communication

Introduction

Named pipes provide a simple and efficient mechanism for inter-process communication in WCF. This article presents a minimal example of how to use named pipes with WCF. It covers the essential steps for creating both a server and client application that can communicate via named pipes.

Server Application

To configure the server endpoint to use named pipes, replace the HTTP binding with a named pipe binding. For instance, the following configuration can be used to create an endpoint that listens on a named pipe called "MyNamedPipe":

<endpoint address="net.pipe://localhost/MyNamedPipe" binding="netNamedPipeBinding" contract="ICalculator" name="NetNamedPipeBinding_ICalculator">
    <identity>
        <userPrincipalName value="OlegPc\Oleg" />
    </identity>
</endpoint>

In the hosting code, add the following line to open the service host:

selfHost.Open("net.pipe://localhost/MyNamedPipe");

Client Application

To generate a client that uses named pipes, add a reference to the service contract and configure the client binding as follows:

EndpointConfiguration config = new EndpointConfiguration(baseAddress + "NetNamedPipeBinding_ICalculator");
config.Binding = new NetNamedPipeBinding();

Conclusion

This minimal example provides a basic understanding of how to implement WCF communication using named pipes. By eliminating unnecessary configuration and focusing on the core functionality, it allows you to quickly integrate named pipes into your WCF applications.
