Whenever I see J.D. Meier's name on a document, I immediately check it out. For example, way back when, "Building Secure ASP.NET Applications" appeared on the ASP.NET 1.0/1.1 scene and it is chalked full of good information that all ASP.NET developers should know. It's a 600+ page book and you can download the PDF for FREE!
With VS2005 and ASP.NET v2 coming down in the near term, Microsoft is really gearing up with the technical direction. BAM! J.D. and the gang have released ASP.NET 2.0 Security Practices At A Glance and ASP.NET 2.0 Security Guidance Index. This is always good stuff. Consider the following HOW-TO's list covered in the document. If developers know the topics in this list, they will add value to their projects and it's a great way to learn about .NET security capabilities.
