Undelete Entity in WCF

Question

I have a WCF-client consuming a OData service. At some point the user can delete an entity. I do this with the DataServiceContext.DeleteObject(object entity) method. So the Entity.State becomes Deleted.

The user has the possibility to undo the deletion. How can I make the state back to Modified?

Answer 1

I finally achieved to do it by:

DataServiceContext.Detach(obj);
DataServiceContext.AttachTo("EntitySetName", obj);

This removed the deleted status from the object and added it as modified.
