i am writing a simple
CMS over ASP.NET MVC framework (for college final project).my problem is with module's data-migration strategy.as each module will update the database schema when it is installed , a database migration mechanism must be implemented in module installation system.ok ,
data-migration in entity framework is already there (thanks to MS) , but the migration commands run in package manager console.is there any way to run a
Data-Migration code Programmatically?
any help is very appreciated.
This class exposes the EF migrations in code:
In EF, migrations work on a whole database though - not modular parts of one.
Just found this class too:
If you've enabled the automatic migrations in Package Manager Console you can use the following code in an init section of your app (e.g. in SimpleMembershipInitializer):
var migratorConfig = new Migrations.Configuration(); var dbMigrator = new DbMigrator(migratorConfig); dbMigrator.Update();
Where Migrations.Configuration is the migration configuration class placed in your project into your namespace (YourProjectNamespace.Migrations).
If you use it programmatically you should at first turn off the EF initializer:
The thing is the programmatic update creates a database if it doesn't exist.
