This paper, covering how to migrate an ASP.NET 1.1 app to 2.0, taking advantage of new 2.0 features like the membership provider, System.Transactions, and so on, was just published last week.  This paper will be of interest to anyone who has ASP.NET 1.1 code, and wants to see how to modify it to take advantage of 2.0.   The paper uses the ASP.NET Petshop as the basis for the examination.

There is a nice interop angle - the code includes an ASP.NET 2.0 membership provider for Oracle 10g.  Also of course, System.Transactions interop with 10g.

Check it out, if you plan to use Oracle with ASP.NET 2.0.
