IT:AD:Code First:Entities:Properties

MUST: mark Scalar Properties as virtual to enable improved Change Tracking (by going from Snapshot CT to Proxy POCO Change Tracking, which is based on IPOCO/IEntityWithChangeTracker).
MUST: mark Collection Navigation Properties as virtual to enable lazy loading.
MUST: Navigation Collection properties must implement ICollection<Entities>
SHOULD: As we are working with proxies, can use private set for Id, etc:
- public string Id {get; private set;}
CONSIDER: For properties that need to ignored:
- DataAnnotations: [Ignore] (see IT:AD:Code First:DataAnnotations).
- FluentAPI: within DataContext.OnModelCreating(): modelBuilder.Entity<Department>().Ignore(t => t.Budget); (see IT:AD:Code First:FluentAPI:Properties)
CONSIDER: For derived calculated properties that need to be saved, use empty sets:
- public FullName {get {return _first + " " + _last;} set {}}
  * CONSIDER: If you have to turn of Id autogeneration:
- DataAnnotations: ? (see IT:AD:Code First:DataAnnotations)
- FluentAPI: within DataContext.OnModelCreating(): modelBuilder.Entity<Dept>().Property(t => t.ID).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None); (see IT:AD:Code First:FluentAPI:Properties)
