entity framework database first working on models

Question

I am using entity framework db first. how do I add data annotations to the model without putting it into the auto generated model?

I want to avoid losing the work I have done, in case I need to add a new column to the table.

Any small explanation or link would be helpful for me to understand.

thanks,

Andy

You can use a second partial class that is created by you which includes the data annotations you like.

I think Code first migrations is what you are looking for.

thank you Biplov13. i may change to code first later on. I am testing database first currently. think code first makes more sense as you can do much more and get more control. I am trying to understand the benefits of db first.thanks :) – Andreas Peiris Feb 24 '14 at 21:34
