the Change Tracker API and validate changes to your data with the Validation API. With

objects or graphs of objects and their related data. You’ll find numerous C# code samples to
help you get started. All you need is experience with Visual Studio and database management
basics. * Use EF’s query capabilities to retrieve data and use LINQ to sort and filter data *
Learn how to add new data and change and delete existing data * Use the Change Tracker API to
access information EF keeps about the state of entity instances * Control change tracking
