DbMigration.AddPrimaryKey Method (String, String, String, Boolean, Object)

[This page is specific to the Entity Framework version 6. The latest version is available as the 'Entity Framework' NuGet package. For more information about Entity Framework, see msdn.com/data/ef.]

Adds an operation to create a new primary key. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc.

Namespace:  System.Data.Entity.Migrations
Assembly:  EntityFramework (in EntityFramework.dll)
