  • Continuation-Passing Mnemonics

    Continuations provide a means whereby heap space can be traded for stack depth (heap space being generally more plentiful than stack depth). They are especially useful where tail recursion is not possible. Here are a couple of simple continuation examples that can be extended to cover more complex scenarios.

  • ObservableObject

    The ObservableObject type implements the INotifyPropertyChanged interface used in WPF and Silverlight to notify on changes to properties that are bound to a control. Specify property names type safely using F# Quotations, i.e. <@ this.PropertyName @> when invoking the NotifyPropertyChanged method. If you are following the MVVM pattern then your View Model class can inherit from the ObservableObject type.

  • Active pattern for let binding inside patterns

    The Let active pattern demonstrated by this snippet can be used to assign values to symbols in pattern matching. This is useful for writing complex pattern matching using match as we can handle multiple cases using a single clause.

  • 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.
