I'm thinking of writing simple application for Windows Mobile devices, where user could simply enter destination coordinates, and the app would calculate distance and show direction to the destination.

But I haven't found any Free, preferably Open Source library with simple API to work with GPS.

There's a sample GPS app in the Windows Mobile 5.0 SDK, but you'll need a fix for it.

They are also in the WM6 SDK's, fix 'corrected'

There are a set of GPS classes in the OpenNETCF serial library.

I recently used open source SharpGPS. It's supposed to support more devices than the example in the SDK, but both solutions work on all my hardware.

SharpGPS did make it easier to access more structured information, such as satellites in view and where they are, and has a brilliant example app. But most of this will go unused in apps that need GPS info.

GPS.NET is now available free on CodePlex.

As an employee of a company who uses GPS.NET (and did, before it went free) I recommend it. I haven't tried the open-source version, but the version we're working from is nice.
