    "Code Behind" = Less Spaghetti Code, MORE SCATTERED Code

    Web site discussing the "increased" DNA Architecture Design Complexity with
    Visual Studio.NET

    DNA Layers and "Code Behind" Towers

    Any comments appreciated. (Oh, just flame away if you want to.)

    Yes, I can your point about having 2 .aspx pages accessing the same business
    logic. And then having to write the logic in 2 places.

    I address that by having the options with that Right Click Menu to make
    "clones of that business logic on both of those aspx pages. Also, I have an
    option to update all the clones of that same business logic across all pages
    of the web site.


    Can you see what I am suggesting?

    Thanks for the feedback.
