Is there any difference of behavior you can see between the two ? If yes that makes sense, otherwise that doesn't. ...

In Windows Phone 7 / Silverlight, is the following code safe or is it a race condition? //Snippet 1 foreach(var item in list) { Deployment.Current.Dispatcher.BeginInvoke( () => { foo(item); }); } Surely (?) this alternative is racy? //Snippet 2 Deployment.Current.Dispatcher.BeginInvoke( () => { foreach(var item in li...

Back in the good ol' Windows Mobile day (CE based) one good get a rough estimate of battery life using the CE CoreDll.dll. Well sometimes at least depending on your hardware. This was exposed via GetSystemPowerStatusEx. WP7 being SilverLight based I'm assuming these sorts of Interop approaches will no longer work. Is there an API that e...
Icons have been provided in the SDK for either "Light" or "Dark" depending on the theme set on the phone. On the application bar when the theme changes the icons automatically change with it. Also, when you press the button the image is reversed (so it's still visible) no matter which theme you're on. I can easily figure out how to chang...

Is there any way in Phone7 to rename a file? I don't see anything in IsolatedStorageFile that exposes this functionality but perhaps I'm missing something? It seems like the best way to rename a file is to read its contents and write them to another file and then delete the original. ...
I'm using Expression Blend 4 to prototype a Windows Phone 7 app. I have a page that is supposed to display a news story. I'm having difficulty getting it to scroll down all the way in the emulator.
