customizing some auto generated codes with T4

Question

I Used "EF 4.x DbContext Fluent Genarator" to generate my poco classes , mapping files and also Context file, in EF Code first.(in fact "EF 4.x DbContext Fluent Genarator" uses 3 T4 files) now i want apply some changes on auto generated codes:

1. change namespace of some classes.
2. Mark some fields of some classes as [NonSerializable]
3. change body of Some auto generated custom methods on pocos that i added to T4 template.

how can i do these works with continuing using T4 files?

Answer 1

for #3. this should help

These classes are partial classes so you can create a new .cs file with same class as partial. add custom methods.

I can not think a straight forward way for #1. & #.2 becase Changes to Auto generated classes will be lost when someone updates / build it again.
