How is a database schema change applied in entity framework using code first without migrations -


I do not want to use migration at this time, but the first code.

When I use Model Builder and create a new table with database properties, Fluent API

How do I say "Apply changes now" when the first query hits the database What changes are made then? Or is there any other better way?

There are many in your settlement, any one you use may differ based on your overall development goals. - Will be different.

Initial is the most flexible of your options, so that you can add your model incrementally. This "migration" process is sometimes also known as "Data Motion".

Another option is available to you, which is the default strategy in this strategy, for the first time when you access any category that requires database access, the database will not exist . If the database already exists, then nothing will happen if the database schema does not match the model, the transaction will fail and the error will be thrown too.

Another popular initiator is the implementation of the ID Base Initiator that will change the model since the database was created, then it will remove the database, rebuild and optionally Again will give the seed.

Finally, you have as much as you can expect, this is the implementation of the IDBS Instifier , which is always rebuilt and will restore the database again for the first time Which is used in any context in the AP domain.
