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.

Building a WPF application in functional way
I started to write pure F# + WPF application in about half a year ago. Today, I found a good way to compose WPF controls with dependent values. It's only writing a dependency object type as a class and give it to constructors of GUI controls. In this snippet "Volume","ColorVolume" and "ShapeContainer" has no properties. But works as a View which represents internal Model and allows users to change internal data. You only need calling a constructor of them. It means that you can compose GUI controls and it's functionality as a immutable data structure. (Update 2011/12/02 8:33:00(UTC+09:00) : Removed some user defined operators and renamed a type similar to DependencyObject in this snippet Reactor to SharedValue.) (Update 2011/12/02 9:04:01(UTC+09:00) : renamed some variables..)

FSX Structure
I use this basic template when writing .fsx files that I might want to compile. It adjusts the difference in command line/entrypoint handling between a script and a compiled assembly. This example shows the details for a WPF script — replace the #r's and/or remove the STAThread for a WinForms or Console script.

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.
