The templates support iHydrateable and I started from the templates you created as an example. Thank you for those. In addition they support custom CBO for tables that can use iHydratable because they don;t have a single integer key.
I've tested a couple with 2.6 and they seem to work, although the Master/Subtemplate system isn't supported in 2.6 so they have to be run individually. This hasn't been exhaustive testing because my focus has been on 5.0 and getting some projects completed. I am considering converting the support subroutines to an assembly to make them easier to debug and that will improve support for 2.6.
Using the master template (DNNMaster) and CodeSmith 5.0 (and 4) you can set up the parameters and it'll generate the entire module, stored procedures, providers, controller, info, view/edit/list ascx's, codebehinds, and resx. It also does a rudimentary master menu.
It will add commentary to the various code elements using the descriptions from the fields and it uses the description information from the database to generate help text in the .resx files.
I should have a version 3 ready soon with some more fixes and enhancements. No C# yet, just haven't had the time.
