A Visual Studio 2005 add-in written by Bill McCarthy that adds appropriate exception handlers to the selected code.
This add-in depends on the latest version (2.0.1) of the DevExpress DX Core library. If you had already installed the free Refactor! add-in, then you'll need to update it so that it is compatible. The links to the latest version are in this post. I think the site has "referrer" detection, so make sure you're already browsing the devexpress site before you try and download.
The final release of version 2.0 is now out
"The Best Practice Analyzer ASP.NET (alpha release) is a tool that scans the configuration of an ASP.NET 2.0 application. The tool can scan against three mainline scenarios (hosted environment, production environment, or development environment) and identify problematic configuration settings in the machine.config or web.config files associated with your ASP.NET application. This is an alpha release intended to gain feedback on the tool and the configuration rules included with it."
