Opened the solution at ch04/WebView01/WebView01.sln
MainWindow.xib opens ok in Interface Builder
Compiles ok

The problem: when I run it I see the message "Waiting for debugger to connect on 127.0.0.1:10000" but it just stays there - the app does not start in the simulator (the simulator itself does start).

I have other apps compiling and running on the simulator, so I know it's not my devevelopment environment/setup. Here are my framework versions (the latest as far as I know) -

xcode_3.2.5_and_ios_sdk_4.2_final 2.dmg
MonoFramework-2.8.2_1.macos10.novell.x86.dmg
monotouch-eval-3.2.3.pkg
MonoDevelop-2.4-r159698.dmg (+ MonoDevelop-20401003.dmg)

I know MonoTouch changes, XCode changes, MonoDevelop changes - so these things happen since you originally wrote the book. This is the first code sample in the book, so I want to make sure I can make this one works before moving on.

Thanks!

Found it: after opening the WebView01.sln click on Project > iPhone Simulator Target > iPhone Simulator 4.2

It was set to "Default" and that did not work.

Good times!
