Unable to use C++ dll in the windows phone 8 application.

Question

Hi folks,
I am trying to use the native c++ dll compiled for Win32 platform using PInvoke. The native dll is a simple library which is returns some dummy values of native data types. The dll is working fine with the traditional Windows Forms Applications. But when
I am trying to use the same dll in the Windows Phone 8 app, I am getting a runtime exception, "An exception of type 'System.NotSupportedException' occurred in Unknown Module. but was not handled in user code".
[System.Runtime.InteropServices.DllImport("win32dll.dll", EntryPoint = "Hello")]
private static extern int Hello();
As one can see the InteropServices classes in Windows Phone 8 sdk, the PInvoke must be supported! am I going wrong some where? Can some one give me sample windows Phone 8 app project which is using native C++ dll.

Here's the official list of InteropServices classes supported by the phone:

DllImport isn't one of them.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
