Ward Bell just told me about this little gem. IdeaBlade has an upcoming MSDN Magazine webinar entitled "Introduction to the Entity Framework and LINQ". LINQ is the new query language that is shipping as part of .NET 3.5 and provides language constructs for querying and filtering in-memory objects. Entity Framework, which is also part of .NET 3.5 provides an ORM layer for business entities. These are both two technologies that will be very significant in the client space. It's likely that you'll be seeing guidance in the future around both coming out of p&p.
If you are interested in ramping up on either of these new technologies then I recommend checking it out. The event takes place on Tuesday, Feb 26th at 2PM EST. You can register here
