As Chris points out, we are coming up on our next Customer Service Release for MapPoint Web Service.
There are some great updates you have been asking for included in this CSR2 release, including:
We will release an updated SDK on MSDN when MapPoint Web Service CSR2 is released to the web shortly. That will include full documentation for all the new and improved features along with some bug fixes to the SDK.
As well, since Virtual Earth Map Control and Windows Live Local rely on MWS for their geo-coding, map data and other features, they will benefit from the updates as well. VE Map Control and WLL will get improved US geo-coding immediately. And they will get the new map data when we refresh our pre-rendered tiles soon.
