Session: How to Refresh an Entity

To update an entity with the latest changes from the server, use the Refresh method from Advanced session operations.

Syntax

void Refresh<T>(T entity);
Parameters
entity T Instance of an entity that will be refreshed

Example

Employee employee = session.Load<Employee>("employees/1");
Assert.Equal("Doe", employee.LastName);

// LastName changed to 'Shmoe'

session.Advanced.Refresh(employee);
Assert.Equal("Shmoe", employee.LastName);

Remarks

Refreshing a transient entity (not attached) or an entity that was deleted on server-side will result in a InvalidOperationException.
