QR code reader for Windows Phone

Question

I'm working on a Windows Phone app and I need a simple QR code reader. I'm following a tutorial.

I did everything, and now I must add

private PhotoCamera camera;

But there is always this error:

The type or namespace name 'PhotoCamera' could not be found (are you missing a using directive or an assembly reference?)

Why am I getting this error?

Answer 1

Make sure you added using :

using Microsoft.Devices;

because PhotoCamera class is available from Microsoft.Devices namespace. Otherwise you'll need to use fully-qualified class name :

private Microsoft.Devices.PhotoCamera camera;
