Hooking up System.Reactive 4.1.2 to new LINQPad.Controls events throws exception on Subscribe

llewelyn

Hi,

I'm attempting to hook up the TextBox.TextInput event using System.Reactive, but keep getting the Exception: ArgumentException: Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type. Is it simply too late at night? What am I missing?

Namespace imports:
LINQPad.Controls
System.Reactive
System.Reactive.Linq

void Main()
{
   var textBox = new TextBox();
   var observable = Observable.FromEvent(h => textBox.TextInput += h, h => textBox.TextInput -= h);
   observable.Subscribe(o => o.Dump());
   textBox.Dump();
}

I've figured it out. For this to work I need to use Observable.FromEventPattern.
