Type Parameters
- TSource
The type of source.
- TWindowClosing
The type of window closing.
Parameters
- source
Type: System.Reactive.Linq.IQbservable<TSource>
The source sequence to produce windows over.
- windowClosingSelector
Type: System.Linq.Expressions.Expression<Func<IObservable<TWindowClosing>>>
