I will be speaking at DevDays 2006 here in Sweden next week on the topic of migrating Asp.Net 1.1 applications to Asp.Net 2.0. It is an interesting topic especially when you really start looking under the covers at what has changed at a lower level. The whole session will be recorded and may be made publicly available at a later date.
For anyone else who is interested in this topic these are some of the resources I have used for my presentation:
What’s New in ASP.NET
ASP.NET 2.0 Internals
Codebehind and Compilation in ASP.NET 2.0
Master Pages in ASP.NET 2.0
Understanding Page Inheritance in ASP.NET 2.0
Migrating from ASP.NET 1.1 to ASP.NET 2.0
