EasyDiagram.NET 1.3 BETA

http://www.EasyDiagram.net

A custom composite control using pure AJAX and Javascript to provide real-time diagram and flowcharting to your asp.net 2.0 pages. Unlike most commercial products that I've seen, EasyDiagram.NET offers a smooth real-time redrawing of node hierarchy.

EasyDiagram.NET can be imported into your toolbox for use on your webforms. The component is 100% C# and implements ICallBackEventHandler for AJAX processing.

Finally, with the beta release of EasyDiagram.NET, the control should be usable with minimal effort. I understand that more documentation is needed, and it is forthcoming.

Free Patterns and Practices Guidance Explorer for ASP.NET and .NET

http://weblogs.asp.net/scottgu/archive/2006/06/29/Free-Patterns-and-Practices-Guidance-Explorer-for-ASP.NET-and-.NET.aspx

JD Meier from the Prescriptive Architecture Guidance Group (aka PAG) at Microsoft stopped by my office this morning to show me the new Guidance Explorer tool he has been working on. This is a cool WinForms client application that aggregates PAG guidance and suggestions, and allows you to search and sort across it. This makes it ideal for quickly reviewing checklists of suggestions for ASP.NET projects. Each guidance rule covers why it should be followed, and includes instructions on how to implement it.
