I’ve just completed posting the WiE community project to CodePlex. As this is my first CodePlex project I expect that I may have forgotten some steps so please let me know of any issues you experience and I will work to resolve them quickly.
You can find the project at: http://www.codeplex.com/wie
In the coming weeks I will put together some documentation for developers interested in and willing to contribute to the CodePlex project and turn this sample into a full fledged location-based social networking application.
Until then you can refer to previous blog articles for a review of the design and implementation of the current WiE release:
Here is a very high level architecture diagram of the components and underlying technologies that make up the current release of WiE.
Have a great holiday and a wonderful new year.
