1. Navigate to the solution file (*.sln), and double-click it. By default, the solution files are copied to the following folders:

   C:\Program Files\Windows Mobile 6 SDK\Samples\Common\CPP\Win32\GetPhoneNumber

   Microsoft Visual Studio 2005 launches and loads the solution.

2. Build the solution (Ctrl+Shift+B).

3. Deploy the solution (F5).

For this sample, it is assumed that the mobile device uses a SIM with the device's phone number programmed into it. Some devices do not store their phone number on a SIM. For these devices, there is no way to programmatically determine the device's phone number and this sample will not successfully return the number.

This application does not need to run Privileged (i.e., it does not need to be signed with a certificate from the privileged store).
