Entity Framework 7 Interceptor

In Entity Framework 6, exists Interception using System.Data.Entity.Infrastructure.Interception, but don't find in version 7 of the Entity Framework.

Here's an example -> https://azure.microsoft.com/en-us/documentation/articles/web-sites-dotnet-entity-framework-row-level-security/
