• Implementing active objects with a MailboxProcessor

  Mailbox processors can easily be used to implement active objects. This example shows how to do that with a reusable wrapper type and minimal boilerplate code in the actual class definitions. Supports both asynchronous calls and synchronous calls. For the latter case, exceptions are automatically propagated back to the caller.

• Dynamic operator using Reflection

  Demonstrates how to implement the dynamic operator (?) using .NET Reflection. The implementation supports calling constructors, propreties and methods using simple overload resolution (based on parameter count). It handles instance as well as static members.

• WPF / SilverLight Converter II

  version 1 is http://fssnip.net/62. This new version support convert from any existing function to a converter function by using composition and pipeline. The convert function is to make the function signature agree to the IValueConverter interface. You can add new functions in the FunctionLibrary module and reuse the class definition to reduce the coding effort. The first sample is to show how to make the converter pipeline work, the second one is a debugger converter used to debug the data binding problem.

• 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.

• 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.
