  • Composable WCF Web API using Async

    A functional wrapper around the new WCF Web APIs (http://wcf.codeplex.com/). Composition is achieved through the use of the HttpRequestMessage -> Async signature. Pushing the app calls in the MessageHandler intercepts all requests and allows you to take control at the earliest point possible before operation selection occurs. Extending this slightly to call the innerChannel's SendAsync would allow you to create a middleware layer that would work both with this and other, normal Web API services.

  • The Haskell const function

    The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.
