public class DropCreateDatabaseIfModelChanges<TContext> : System.Data.Entity.IDatabaseInitializer<TContext> where TContext : DbContext
type DropCreateDatabaseIfModelChanges<'Context (requires 'Context :> DbContext)> = class
    interface IDatabaseInitializer<'Context (requires 'Context :> DbContext)>
