Open Source C# Networking Software for Windows

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

IIOP.NET allows a seamless interoperation between .NET, CORBA and J2EE distributed objects. This is done by incorporating CORBA/IIOP support into .NET, leveraging the remoting framework.

A distributed, peer-to-peer, server-less communication & messaging solution for JAVA (JMS), C++ and .NET applications, integrates with JBoss, WebLogic & WebSphere. Offers guaranteed delivery, security and transactions. Supports TCP, SSL & HTTP protocols.

Open, fast, robust grid for distributing computing, processes etc. A great alternative to overpriced commercial products such as DataSynapse. Not constrained by standards: contribute to invent new grid computing.

NGrid is a transparent C# .Net/mono grid computing model. NGrid abstracts the burden of the grid into a simple multithread and garbage collected programming model. NGrid is designed to carry computationally intensive tasks over multiple machines.

.NET VNC Viewer is a VNC viewer written entirely in C#. It is binary compatible with Smartphones, Pocket PCs and Windows desktops (.NET CF or .NET Framework). I write this because other VNC viewers on Pocket PC do not do full screen and screen rotation.

Note: There is a successor of AsyncWcfLib: https://github.com/steforster/Remact.Net AsyncWcfLib is a software library for distributed computing based on Microsoft WCF. AsyncWcfLib is a lightweight message bus bridging Windows and Linux by using the .NET Framework or Mono. It supports callback based asynchrony as well as the new async-await pattern available in .NET 4.5. AsyncWcfLib supports threadsafety through an actor based programming model. Actors are loosly coupled system units interacting by passing messages. Message objects are passed inside a process between actors running on different threads. Also, messages may be passed between actors running on different processes, hosts and operating systems. The library is designed for configuration free, asynchronous messaging. A router application is included. It discovers actors by their name on any linked host, even when host name resolution is not possible because of routing- or operating system limitations.

Sxta is a C#-based component architecture for distributed simulation on P2P systems. It is based on Std. IEEE 1516 as distributed simulation Standard. Sxta uses AOP mechanisms that generate classes at runtime inheriting from base ones.

A server emulator for World of Warcraft, providing the ability for individuals to create their own realms, customised through an easy-to-use C# scripting system, allowing one to create AI, items, quests, and any other in-game functions with ease.

User Interface for Sysinternals excellent "psExec". Use it to execute multiple tasks on multiple machines.

mDNS.NET is an implementation of the Multicast DNS (mDNS) protocol (also known as Rendezvous) for service registration and discovery on a local network in the C# language. mDNS.NET is designed for both the Microsoft .NET Framework and the mono framework.
