Integrating Google Maps into an ASP.NET page

While Microsoft have released their new Virtual Earth ASP.NET Control, I still haven't found a decent wrapper that converts addresses to langitude and longitude co-ordinates. There is a Geo coder web service available here (this shows the co-ordinates for the White House) but it seems to only work for US addresses, which doesn't help me at all. So for the moment, I'm still using Google Maps, and have prepared the following to show you how to integrate Google Maps into your ASP.NET pages.
