IndexOperation Class

Definition

Namespace:
System.Data.Entity.Migrations.Model
Assembly:
EntityFramework.dll

Common base class for operations affecting indexes. 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.
