Lei,
Based on the document at (watch for line wrap):
http://msdn.microsoft.com/netframewo...qprojec_topic6
In the section titled "SQL Integration", it states:
To issue a query against a relational store, the DLinq implementation of the
LINQ pattern translates the query from its expression tree form into a SQL
expression and ADO.NET DbCommand object suitable for remote evaluation
So basically, its constructing a query that is sent to the server. I
can't imagine that they would not open this up to other data providers (as a
matter of fact, you could probably do it on your own with the bits that they
released).
It just so happens that they targeted SQL Server first (I wonder why,
haha).
Hope this helps.

1) Is it support other database other than SQL Server, such as Oracle,
Sybase?
2) How about the performance? Does it relay on reflections to bind the
value from databse to Entity object?
Thanks!
