I recently wrote up an article that discusses best practices for versioning and deployment of .NET components. In the article, and in my sessions on this subject I emphasize code access security, running with least privilege, versioning issues, publisher policies and more. Check it out here: http://www.15seconds.com/Issue/041103.htm

On a related resource page, you can find the tutorial I wrote for the code sample: http://www.dotnetdashboard.net/sessions/versiondeploy.aspx

This month, you can expect an article explaining .NET runtime security and sandboxing.

Cheers!
