SQL Linked Server - lessons learned

I plan to post scripts showing how to create a linked server to SQL Server Express 2008 R2 (link an access db) - with two CLR classes, System.Data.OleDb and System.Data.SqlClient

But first, lessons learned.  (1) I was not really dedicating time to the scripts. Just tried to quickly adapt a working COM/ADO script. (2) I relied too much on C# and Powershell scripts, and seemed to think that o = ObjectClrNew("System.Data.SqlClient") was appropriate, therefore confusing the namespace with a class (an assumption based on looking at C#) (3) I do know the difference between synchronous and asynchronous.... and by looking into both the OLEDB and SQLClient classes, see that the latter supports asynchronous which begin with "Begin".

I expect to be writing scripts for a real SQL Server (not my local Express) so there is a lot more testing as I want to link/unlink local Access and Excel files to perform specialized queries combing Server and local data.

I feel like a lot of the young people today who say "I know how to drive, but I'm used to automatic, and the standard shift confuses me".  Been spoiled by successes with COM.
