Q:

Developing asp.net application, use Google maps or bing maps?

I need to use a map in an application that I develop. In my application I want to use pins that will show infoboxes on the map. Use the zoom in, zoom out functionality and the ability to show several maps on the same page. I won't need to use the search locations or routing directions.
Which type of maps should I use? Google or Bing? As I understand, they both have good user interface, but which one is easier to develop with? If I'll use Bing then will it be more Microsoft like, I mean, it will let me use visual studio convenient programming? More or less javascript so it will be a hassle do debug it?

A:

In truth it doesn't matter.  They'll both get you the same results.  What you need to look as it the licensing agreements between the two of them.  That is going to be your real deciding factor. 
Personally, I like Bing better, but that is entirely my opinion.  People who are really good with Google will tell you it is easier.  It all depends on what you are used to and what you like.  I would quickly mock up both and see which is better for you.
I would check here.  It is a comparison between the two and the writer's breakdown of what he experienced.

Sorry I don't have examples of Google's.  I haven't used it a while.
