Session : How to Get Entity Last Modified

When a document is downloaded from the server it contains various metadata information, including the last modified date of the document.

Last modified date is stored within the metadata in session and is available for each entity using the GetLastModifiedFor method from the Advanced session operations.


DateTime? GetLastModifiedFor<T>(T instance);

instance T Instance of an entity for which the last modified date will be returned.
Return Value
DateTime? Returns the last modified date for an entity. If the instance is transient, it will load the document from the server and attach the entity and its metadata to the session.


Employee employee = session.Load<Employee>("employees/1-A");
DateTime? lastModified = session.Advanced.GetLastModifiedFor(employee);
