DataServiceContext.WritingEntity Event

Occurs after an entity has been fully serialized into XML in a request message.

Namespace:  System.Data.Services.Client
Assembly:  Microsoft.Data.Services.Client (in Microsoft.Data.Services.Client.dll)
Public Event WritingEntity As EventHandler(Of ReadingWritingEntityEventArgs)
Dim instance As DataServiceContext 
Dim handler As EventHandler(Of ReadingWritingEntityEventArgs)

AddHandler instance.WritingEntity, handler

Handling the WritingEntity event enables you to change the XML in a request before it is sent.

The WritingEntity event may occur on a different thread when you call BeginSaveChanges(SaveChangesOptions, AsyncCallback, Object) without including Batch in the supplied SaveChangesOptions value.
