For consistency: add-migration after applying validation rules

It's worth mentioning that some validation rules must be applied to the DB schema for consistency by adding a new migration. e.g. add-migration AddingNewRules

Mainly, the following two attributes affect the schema: 1- [Required] will alter the relevant column and make it not null 2- [StringLength(60)] will alter the type of the column and make it nvarchar(60)

I used Visual Studio Tools>NuGet Packet Manager > Packet Manager Console PM>Add-Migration AddNewValidationRules (I used a different migration name than the suggestion above left in the comments)

That scaffolds a migration.
