Examples

Folder	What it holds
Documentation/Pages/<page>	One console project per page of the ReactiveUI handbook. Each snippet on a page comes from its project.
Documentation/Common	The apps the pages share: a to-do list backed by a store, and a GitHub repository search. Controls are console stand-ins for a button, text box, label and list.
ReactiveUI.Samples.*, ReactiveUI.Builder.*	Complete apps for WPF, WinForms, MAUI and Blazor.

Every documentation project runs. Each example prints what it does, and the // Output: comment under it shows what it prints, so you can compare the two:

dotnet run --project src/examples/Documentation/Pages/commands

Page	Shows
view-models	RaiseAndSetIfChanged, WhenAnyValue, ObservableForProperty, output properties with ToProperty, and a search box that queries as the user types.
commands	Creating commands, CanExecute, ThrownExceptions, InvokeCommand, combined commands, cancelling, and BindCommand.
data-binding	Bind, OneWayBind, conversions while binding, and BindTo.
when-activated	WhenActivated in a view model and in a view, and reloading each time a screen is shown again.
interactions	Asking the view a question with Interaction, handler order, unanswered questions, and BindInteraction.
view-location	Finding a view by its view model, contracts, view modules, and wrapping the view locator.
routing	Navigating, going back, resetting the stack, watching the stack, and finding the view for the current page.

Property observation and binding

WhenAnyValue, ObservableForProperty, Bind, OneWayBind, BindTo, BindCommand, BindInteraction and the view locator come from ReactiveUI.Binding. Its source generator writes each binding and view lookup at compile time, so they need no reflection and are safe to trim. The ReactiveUI package imports the ReactiveUI.Binding namespaces for you, so these calls need no using directive.

The documentation projects reference the ReactiveUI project, which does not import those namespaces the way the package does, so Documentation/Directory.Build.props imports them for each page.
