Estoy tratando de cambiar el nombre de las tablas de identidad a Roles, Users, UserRoles, UserLogins y UserClaims. Paré parcialmente el éxito y el uso del comando Update-Table actualiza mi base de datos.

Sin embargo, parece que no puedo deshacerme de la tabla AspNetUsers, siempre se genera con solo una columna, la columna Id, aunque obtengo otra tabla Usuarios con la lista completa de columnas y otra columna Id.
