asp.net mvc - Changing the structure of my database / edmx model -


i using edmx editor create database visually, whenever change structure, , choose option "generate database model", current data in database wiped.

is @ possible change structure of database, , retain data?

how people work around problem?

thank you

here solutions:

  1. use code first or database first workflow, suggested in comment question. note: can use code first existing database.
  2. maintain data insert script should run after every "generate database model".
  3. make schema changes in database first, use "update model database" instead of "generate database model".

if using code first workflow possibility you, recommend going route.

hope helps.
