    HttpRequester

    HttpRequester

    HTTP request utility designed with developers in mind.

    This program is a custom solution to the problem of requiring the use of a HTTP WebApi or similar resource from a language that lacks support for socket communication. The only requirement of the client language is that it has a standard I/O library and is able to execute system commands. You pass a JSON request body to this CLI tool and it will print a response JSON object to the standard out with usual HTTP response information, status, body, request time etc. See the wiki 'Getting Started' guide to see how to pass in parameters and start using HTTP from those awkward development platforms.

    AsyncWcfLib

    AsyncWcfLib

    Actor based programming using WCF and async-await.

    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.
