Lawrence ,
Any additional feedback on your last post? I agree and have been very unimpressed with the lack of uniformed information regarding the Bing Extension (the link the SDK doesn�??t work). I have only been researching this topic for a day or so, but I am not even sure how to access the Bing Maps Extension.
Our agency has standardized our API framework as JS API and dojo. We have recently started to use the Bing Maps key to reference the Bing basemaps. However, we have other developers in other sections that are using the Bing Maps Ajax V7 API and it is unclear to me if those developers can leverage any the Bing Extension for ArcGIS.
Thoughts,
Chris
