Class RunnableWrapper<TView, TResult>
Wraps any View to make it runnable with a typed result, similar to how FlagSelector<TFlagsEnum> wraps FlagSelector.
public class RunnableWrapper<TView, TResult> : Runnable<TResult>, IDisposable, ISupportInitializeNotification, ISupportInitialize, IRunnable<TResult>, IRunnable where TView : ViewType Parameters
TViewThe type of view being wrapped.
TResultThe type of result data returned when the session completes.

Remarks
This class enables any View to be run as a blocking session with Run(Func<Exception, bool>?, string?) without requiring the View to implement IRunnable<TResult> or derive from Runnable<TResult>.
Use AsRunnable<TView, TResult>(TView, Func<TView, TResult?>) for a fluent API approach, or RunView<TView, TResult>(IApplication, TView, Func<TView, TResult?>, Func<Exception, bool>?) to run directly.

// Extract result when stopping
