Hi,

Try http://www.entityframeworktutorial.net/code-first/seed-database-in-code-first.aspx

EF can create the database for you and "seeding" just means inserting some initial data when the db is created (for example if you have a country table you may want to pre-populate this table with default countries etc...)

suppose by EF we create a country table with two fields named ID and Name and seed with some initial data but we add more country data there. after few days we decide to add one more column in that table called culture by code first then what will happen..........my all data will be lost?

what option we need to turn on as a result data should not be lost. if possible please discuss.

thanks

No, the ALTER TABLE MyTable ADD <column definition> statement allows to add a new column to an existing table. You can drive this through EF using https://msdn.microsoft.com/en-s/data/jj591621.aspx
