Unable to launch CameraCaptureTask or PhotoChooserTask while debugging with device

I'm trying to debug my application on the connected device*(Dell Venue Pro WP 7.0)* but whenever I try to launch CameraCaptureTask or PhotoChooserTask in my app then nothing ha开发者_运维百科ppens. Everytime I've to disconnect the device from the Zune and then app works fine. But I want to debug my app on device. I'm not able to figure out what is happening there. No Exception , No Errors ?

You can't use the Camera or the Photo Chooser while you're connected with Zune.

Instead, connect the device, shut-down Zune, and start WPConnect.exe, and then you can deploy&debug, and still use the Camera, Photo or even Music if you want to.

You can find WPConnect in either the x86 or x64 folder in

C:\Program Files\Microsoft SDKs\Windows Phone\v7.1\Tools\WPConnect
