EditLink | Gets or sets the URI that modifies the entity. |
|
EditStreamUri | Gets or sets the URI that modifies the binary property data of the entity. |
|
Entity | Gets the entity that contains the update data. |
|
ETag | Gets an eTag value that indicates the state of data targeted for update since the last call to SaveChanges. |
|
Identity | Gets or sets the URI that is the identity value of the entity. |
|
LinkInfos | Returns a collection of links that are the relationships in which the entity participates. |
|
OperationDescriptors | Gets a collection of operation descriptors associated with the entity. |
|
ParentForInsert | Gets the parent entity that is related to the entity. |
|
ParentPropertyForInsert | Gets the name of the property of the entity that is a navigation property and links to the parent entity. |
|
ReadStreamUri | Gets or sets the URI that accesses the binary property data of the entity. |
|
SelfLink | Gets or sets the URI that is used to return the entity resource. |
|
ServerTypeName | Gets or sets the name of the type in the data source to which the entity is mapped. |
|
State | When overridden in a derived class, gets the state of the object at the time this instance was constructed. (Inherited from Descriptor.) |
|
StreamDescriptors | Returns a collection of named binary data streams that belong to the entity. |

Remarks
The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects each of which contains a sequence of EntityDescriptor or LinkDescriptor instances that represent changes that were persisted.
For successful operations, the State property of the descriptor will be set to unchanged and the new values for insert and update operations will be merged according to the merge settings.
For operations with errors, the State of the descriptor will remain the same as it was before SaveChanges was called.
If an error occurred and processing stopped during an operation, the State will remain unchanged.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
