WPF and Location Services

I'm new to WPF but I managed to build a rather simple project that displays a map with a route for a delivery truck driver.  The application will run on a Microsoft Surface Pro with Windows 8.

I now want to display an icon on my Bing map that will show the current location of the truck.  After doing some research, it seems like I need to use Location Services.  They have an API but I can't seem to find any info on how to install and use this.  Has anyone used this?  I'd like to see the step-by-step tasks I need to do to use this API.

I am using WPF with C#.

Thanks,

Bob
