I updated “funslae” to center the map on your location if Google can figure out your location. The Google AJAX API is used to get your location based on your IP address. There are many other options for geocoding an IP address. The updated example demonstrates how to communicate between JavaScript and Silverlight in F#. The approach is based on a 2008-07 blog post from Mike Snow.
Most of the coding was done in JavaScript in index.html. I updated it to load the Google AJAX API, then the Silverlight control via JavaScript, then center the map by calling the .NET code from JavavScript. In App.fs, I extended Map to create a ScriptableMap that is exposed to the JavaScript.
Let me know if doesn’t work for you.
