Vs Review and Outlook and confused thinking about Expert System Development

We installed vs2008 in the past two days. Let's take a look. It hasn't changed much on the interface with vs2005, but its functions have been improved a lot. It can be said that it has reached my almost perfect ideal two years ago.
That is, I casually said a few words:
What I expect vs2007

Lambda, LINQ to XML, LINQ to SQL, xbap, and Silverlight are the implementations I have always dreamed.
WWF is very good at developing business processes.
There are a few regrets:
1 xbap is difficult to access the database, and the service always feels indecent.
2. The Math library is not supported.
After reading a bit about the expert system and preparing for graduation design as the forestry model and expert system, we found that vs2008 is suitable for expert systems in many places.
1 lambda, LINQ to XML, LINQ to SQL, and data operations can be performed in the memory to minimize the use of external storage (such as databases and files)
2. domain-specific languages (DSL) Facilitate the integration of expert system modules with. net.
3 xbap, Silverlight for web development, hey.

Expectations of related industries:
1. Object-Oriented Database: Read db4o. This little stuff is so elegant,
2. net3.x-based expert system knowledge base (Knowledge Base) and inference engine (inference engine) development tools or shell)
3. Professional models are of course mature forestry models.
4. Improvement of 3D GIS (ARC scene is slow, with rough effects, good skyline effects, data and development capabilities, and the concept of GIS is not strong, the emergence of powerful 3D GIS similar to Google Earth is required)
