How can I change foreign key option on MySQL EF 6?

Question

I created a table with wrong foreign key option in MySQL EF 6 so I want to change foreign key option of that table to CASCADE DELETE, but how to?

I made this database on code-first. Is there any solution without re-creating database or manually call SQL?

then create migration script as you did it earlier.

add-migration AlterMyTableFK

after that Update Database as you did it earlier.

Just make changes you want, then in the "Package Manager Console", execute this line:
