Remarks
It is common to use EnsureCreated() immediately following EnsureDeleted() when testing or prototyping using Entity Framework. This ensures that the database is in a clean state before each execution of the test/prototype. Note, however, that data in the database is not preserved.
See Managing database schemas with EF Core and Database creation APIs for more information and examples.
