Lightweight library for method calls over named and anonymous pipes for IPC in .NET Core. Supports two-way communication with callbacks.

var pipeServer = new PipeServer<IAdder>("mypipe", () => new Adder());
await pipeServer.WaitForConnectionAsync();

var pipeClient = new PipeClient<IAdder>("mypipe");
await pipeClient.ConnectAsync();
int result = await pipeClient.InvokeAsync(a => a.AddNumbers(1, 3));

var pipeServer = new PipeServerWithCallback<IConcatenator, IAdder>("mypipe", () => new Adder());
await pipeServer.WaitForConnectionAsync();
string concatResult = await pipeServer.InvokeAsync(c => c.Concatenate("a", "b"));

var pipeClient = new PipeClientWithCallback<IAdder, IConcatenator>("mypipe", () => new Concatenator());
await pipeClient.ConnectAsync();
int result = await pipeClient.InvokeAsync(a => a.AddNumbers(4, 7));

This library uses named pipes to invoke method calls on a remote endpoint. The method arguments are packaged up in JSON, encoded and sent over the pipe.

• 100% asynchronous communication with .ConfigureAwait(false) to minimize context switches and reduce thread use
• 39KB with Newtonsoft JSON as only dependency
• Invoking async methods
• Passing and returning complex types via JSON serialization
• Interleaved or multiple simultaneous calls
• Throwing exceptions
• CancellationToken support
• Works on Windows, Linux and MacOS

• Methods with out and ref parameters
• Properties
• Method overloads

Let me know if you have any interest in supporting alternate serializers like System.Text.Json, Utf8Json or MessagePack.
