.TT files

I want to make a blog series about what you can do with .tt files. I do not mean now what cen be generated from edmx( I have blogged about that at

http://msprogrammer.serviciipeweb.ro/2010/09/27/generating-history-trigger-with-ef-edmx-and-tt-files/

and

http://msprogrammer.serviciipeweb.ro/2010/06/28/ef-automatic-history-of-table-and-t4-files-tt-files/

)

I will start from a .tt template that will be analyzing a class( the ViewModel in MVC terms ) and then,starting from this template,I will generate:

1. Loading the class from config file( web / app)
2. Generating resx files for translating
3. Generating help / tooltip
4. Generating logging for all methods ( with an _On convention)
5. Generating shallow copy for the class,saving the properties and an Interface ( usually  good for DI / Ioc)
6. Generating

I expect your suggestions too. What do you have iteratively do in your development( MVC ) more than one time for each ViewModel ( Model) class ?

( this is the .tt file)
