Anything that's a web standard (AJAX/JSON, etc) will work.

Microsoft pushes the latest and greatest. Just because you don't see them pushing it doesn't mean it isn't viable.

>Thank you for the example; I will follow the link and see how it applies. I don't know ajax/json so I will have to Google to find more about this approach. One thing I remember that years ago at the local Microsoft office they would have presentations on ajax (quite often). But then in recent years these stopped. So I thought that MS is no longer pushing ajax and now has a different technology instead of ajax. But I will check it out.
