entitySetName

The entity set of the objects in the collection.

entityChangedCallback
Type: System.Func<EntityChangedParams, Boolean>

This topic describes new functionality in ADO.NET Data Services that is available as an update to the .NET Framework version 3.5 Service Pack 1. You can download and install the update from the Microsoft Download Center.

Use this constructor to create an empty DataServiceCollection<T> to which entity objects can be added without executing a query against the service or when an IEnumerable<T> is not available.

By default, automatic change tracking is enabled for a DataServiceCollection<T>. You can create an instance of DataServiceCollection<T> that uses manual change tracking when you create an instance using a constructor that enables you to supply a value of None for TrackingMode. When you use manual tracking, you must implement INotifyPropertyChanged and INotifyCollectionChanged and handle the raise events to manually report changes to the DataServiceContext.
