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.

Simple F# ViewModel for Silverlight MVVM
Silverlight default architecture is Model-View-ViewModel. This code gives full design time support for Microsoft Expression Blend. The F# ViewModel is seen as strongly typed data source in the Blend UI. There are two properties binded to the view: HiLabel (OneWay data binding) and MyName (TwoWay data binding). ViewModel implements the INotifyPropertyChanged to support the binding. The view project (HelloApp) is made with Blend (by designers) and it is Silverlight 5.0 project. The view codebehind is c# file and it has only this.DataContext -assignment. The viewmodel project (HelloApp.ViewModel) is F# Silverlight 4.0 library. It is made with VS2010 and F# (by developers). It contains the logical functionality of the current view.

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.

Growing Tree Algorithm for Maze Generation
There are several maze creation algorithms (http://www.astrolog.org/labyrnth/algrithm.htm). The interesting point about Growing Tree one is that it turns into the others (for example, Recursive Backtracker and Prim's algo) when we choose the next step in different ways. Check it with tryfsharp.org.
