Entity Framework Audit Discover who support this features

Introduction

The audit allows you to log changes from Entity Framework change tracker in a database or log file.

Why Audit?

Entity Framework saves entities in a database but doesn't let you easily track changes. To follow all the changes, you will need to use a third-party library.

Common scenario:

• To keep a history of changes in a database or a log file
• Track What/Who/When a modification occurs
• Show historical data changes in a grid
