CI build	Stable build

A .NET Core 3.1 based lightweight framework for efficient inter-process communication. Named pipeline and TCP support out-of-the-box, extensible with other protocols.

Name	Purpose	Status
JKang.IpcServiceFramework.Client.NamedPipe	Client SDK to consume IPC service over Named pipe
JKang.IpcServiceFramework.Client.Tcp	Client SDK to consume IPC service over TCP
JKang.IpcServiceFramework.Hosting.NamedPipe	Server SDK to run Named pipe IPC service endpoint
JKang.IpcServiceFramework.Hosting.Tcp	Server SDK to run TCP IPC service endpoint

1. Create an interface as service contract and package it in an assembly to be referenced by server and client applications, for example:

   public interface IInterProcessService
   {
       string ReverseString(string input);
   }

2. Implement the service in server application, for example:

   class InterProcessService : IInterProcessService
   {
       public string ReverseString(string input)
       {
           char[] charArray = input.ToCharArray();
           Array.Reverse(input.ToCharArray());
           return new string(charArray);
       }
   }

3. Install the following NuGet packages in server application:

   > Install-Package Microsoft.Extensions.Hosting
   > Install-Package JKang.IpcServiceFramework.Hosting.NamedPipe

4. Register the service implementation and configure IPC endpoint(s):

   class Program
   {
       public static void Main(string[] args)
       {
           CreateHostBuilder(args).Build().Run();
       }
   
       public static IHostBuilder CreateHostBuilder(string[] args) =>
           Host.CreateDefaultBuilder(args)
               .ConfigureServices(services =>
               {
                   services.AddScoped<IInterProcessService, InterProcessService>();
               })
               .ConfigureIpcHost(builder =>
               {
                   // configure IPC endpoints
                   builder.AddNamedPipeEndpoint<IInterProcessService>(pipeName: "pipeinternal");
               })
               .ConfigureLogging(builder =>
               {
                   // optionally configure logging
                   builder.SetMinimumLevel(LogLevel.Information);
               });
   }

5. Install the following NuGet package in client application:

   > Install-Package JKang.IpcServiceFramework.Client.NamedPipe

6. Invoke the server

   // register IPC clients
   ServiceProvider serviceProvider = new ServiceCollection()
       .AddNamedPipeIpcClient<IInterProcessService>("client1", pipeName: "pipeinternal")
       .BuildServiceProvider();
   
   // resolve IPC client factory
   IIpcClientFactory<IInterProcessService> clientFactory = serviceProvider
       .GetRequiredService<IIpcClientFactory<IInterProcessService>>();
   
   // create client
   IIpcClient<IInterProcessService> client = clientFactory.CreateClient("client1");
   
   string output = await client.InvokeAsync(x => x.ReverseString(input));
