Jeff Prosise has done some presentations on ASP.NET 2.0 which you can view as video streams or download them to your hard disk.

In (classic ;-)) ASP.NET 1.1 you had to reference a user control in every page you wanted to use the control in (@Page-directive).

ASP.NET 2.0 lightens this work because it allows you to reference heavily used user controls globally in the web.config file.

When you have added something like this to your web.config:

your user control is avaible in every page of your web project accessing it via

And you have full intellisense support for your user control, of course.

If you really want to know how ASP.NET works, take a low-level Look at the ASP.NET Architecture.

For example, if you have a button or other post-back generating control on a form alongside a GridView, and the effect of the button is to modify the underlying database (say it adds a new row to the table being displayed by the GridView), you won't see the changes made to the database when the page is rendered.

Fritz Onion tells you why and how to solve this issue.

If you're developing ASP.NET 2.0 Pages or User Controls and want them to be re-usable (and maybe pack- and sellable), you should read Scott Guthrie's walk-through how to easily accomplish this with VS 2005.

This page explains the rationale behind the patterns & practices Security Guidance for .NET Framework 2.0 project and provides an index into the guidance. You can use the guidance referenced on this page to improve both the security of your applications and your approach to building secure applications.

The PAG Team has released another guidance offering: The Architecture Testing Guidance Whitepaper, which can be downloaded at the Test & QA Workspace at GotDotNet.

"The patterns & practices Architecture Testing Guide is designed to help project stakeholders, software designers, developers, and testers understand the process of testing software architecture before the code is implemented. The paper describes an approach and methodology for testing the design of a system, and describes the user-specific viewpoints that you must consider during the testing process. The Architecture Testing Guide walks through the process of testing a system from each viewpoint, and provides instructions, examples, and best practices along the way."

In his posting "Some techniques for better managing files in VS 2005 Web Projects" Scott Guthrie explains how to make good use of the new Web Project mode.

It is done: The August CTP of Enterprise Library for .NET Framework 2.0 is now available for download!

Here are some nice tricks when using Google Talk.
