entity framework core - Is it possible to add CHECK constraint with fluent API in EF7?

Is it possible to add CHECK constraint with fluent API in Entity Framework 7?

I need to acheive something like this:

...
ADD CONSTRAINT CK_SomeTable_SomeColumn CHECK (SomeColumn >= X);

It is ok if solution is provider-specific - I am targeting MsSqlServer only (at least now).

See Question&Answers more detail:os

As of EF 7.0.0-rc1, it isn't possible with the fluent API.

You can define the constraint manually in the migration

migrationBuilder.Sql("ALTER TABLE SomeTable ADD CONSTRAINT CK_SomeTable_SomeColumn CHECK (SomeColumn >= X);");
