EF5: Where are my DataAnnotations?

EF 4.x:

EF 4.1+ has a DataAnnotations namespace for the new EF related annotations. Most of them are related to database schema.

EF 5

Not even a DataAnnotations namespace in here. That's because the annotations got incorporated into .NET 4.5.

 

.NET 4.5

A new namespace within System.ComponentModel.DataAnnotations: "Schema"

All of the EF schema annotations are in here now. MaxLength and MinLength are in the DataAnnotations namespace.

Added the following thanks to a suggestion from Cecil Phillip

If you are using EF5 with .NET 4, there is a special version of the Entity Framework assembly which actually has the version 4.4.*.

The EF related DataAnnotations *are* in this assembly but notice they've been organized into regular and schema as they are in  .NET 4.5.
