  • Break sequence into n-element subsequences

    I'm working on parallel computations and I thought it would be useful to break work into chunks, especially when processing each element asynchronously is too expensive. The neat thing is that this function is general even though motivation for it is specific. Another neat thing is that this is true lazy sequence unlike what you'd get if you used Seq.groupBy. There are three versions for your enjoyment.

  • 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.

  • 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.
