Simple C# library for NamedPipe and TCP-based IPC
Written against .NET Standard 2.0, ought to be compatible with most modern .NET versions.
Server usage:
using EasyPipes;
// IService defines the IPC interface
public interface IService
{
int Sum(int one, int two);
}
// Calculator is the server class
class Calculator : IService
{
public int Sum(int one, int two)
{
return one two;
}
}
// start up
Server server = new Server("pipename");
server.RegisterService<IService>(new Calculator());
server.Start();
// eventual shutdown
server.Stop();Client usage:
using EasyPipes;
// IService defines the IPC interface
public interface IService
{
int Sum(int one, int two);
}
// setup client
Client client = new Client("pipename");
IService service = client.GetServiceProxy<IService>();
// execute remote operation
int result = service.Sum(6, 12); // = 18Encrypted TCP:
using EasyPipes;
/// IService defines the IPC interface
public interface IService
{
bool Authenticate(string username, string password);
string GetSecretData();
}
// --------- SERVER --------------
class StatefulService : IService
{
private bool has_authenticated = false;
[EncryptIfTrue]
public bool Authenticate(string username, string password)
{
if(Authenticated(username, password))
{
this.has_authenticated = true;
return true;
} else {
return false;
}
}
public string GetSecretData()
{
if(has_authenticated)
return somesecretstuff;
else
throw new Exception("Not authenticated");
}
}
// start up
TcpServer server = new TcpServer(new IPEndPoint(address, port), new Encryptor(sharedkey));
server.RegisterStatefulService<IService>(typeof(StatefulService));
server.Start();
// eventual shutdown
server.Stop();
// --------- CLIENT -------------
// setup client
TcpClient client = new TcpClient(new IPEndPoint(address, port), new Encryptor(sharedkey));
IService service = client.GetServiceProxy<IService>();
// authenticate (transmitted in plaintext!)
if(service.Authenticate(username, password))
{
// transmit encrypted messages
string data = service.GetSecretData();
}Remarks:
- By default there is a single instance of the server class used by all clients! Use the stateful service for service which require an instance per connection.
- It's primarily focussed on IPC on single-machine or swift LAN-connections, so it likely will not perform well with long-distance internet connections.
- Any and all arguments or return values are serialized using DataContractSerializer, so custom types that need to cross the connection should be designed accordingly.
- Provides optional AES256 encryption for TCP connections upon call to a labelled service method, for example after authentication

In simple terms: You can use the library as-is for any of your own projects, but any changes to the library itself have to be available under the same terms.
