I created a xaml Item exactly the same as Histogram.xaml havent change anything ! (I wanted to start by keeping things the same)
But still it's not working, the problem is here :

this

.cameraViewBrush.SetSource(this.Camera);

it's not giving me any feedback !
I can't find any clues to help me fixing this, any guidance is appreciated !

the problem is that you downloaded the zip from internet so it is marked as unsecure. open properties of the zip and hit "unblock" in the right lower corner. then you can unzip abd run the project. bye

I solved my problem by compiling the WriteableBitmapExWinPhone.dll from the source code by myself. I couldn't find any other solution.

Thank you for the clear and helpful examples. I'm getting this sort of error each time I try to run the application:

"Error 2 Could not load the assembly file:///C:\WriteableBitmapExWinPhone.dll. This assembly may have been downloaded from the Web. If an assembly has been downloaded from the Web, it is flagged by Windows as being a Web file, even if it resides on the local computer. This may prevent it from being used in your project. You can change this designation by changing the file properties. Only unblock assemblies that you trust. See http://go.microsoft.com/fwlink/?LinkId=179545 for more information. SLPG.Mango.ManipulateCamera"

I don't know what's wrong. The dll is not blocked if I check the file properties. Any help is really appreciated.

Ah yes! I figured that out late last night (config mgr chgs). Thank you for confirming.

I also have another nasty HW problem, my USB port on my Focus is corroding and causing connection problems, that certainly wasn't helping neither! DOH!

Thank you for your blog on this. The specific hiccup I'm trying to solve right now is usign the LED always on. I can make it flash, but I would like to control the flash to be on 100% of the time. I've seen one flashlight app do it, but i don't know why.

Hi phenry, you need to go to the Configuration Manager and activate the "Build" and "Deploy" flags for the projects you need to run. This is because I deactivate old project while adding the new to avoid multiple deploy during the development.

Thanks

I'm not sure what is happening, but I'm unable to run this no matter what I do. I keep getting "The application could not be launched for debugging. Ensure that the target device screen is unlocked and that the application is installed." I also realized that only one project is built with an F6, the rest are not, even after doing a manual build on those other three, I get the same dialog. Am I doing something wrong? (and no, my Focus is unlocked and running haha)
