Session : How to mark entity as readonly?

Entities can be marked as read-only using MarkReadOnly. This operation is equal to adding to entity metadata a key Raven-Read-Only with value set to True.

Implications of setting entity as read-only are as follows:

• change tracking won't apply to such entity
• forcing updates or deletes (e.g. using Commands) will throw OperationVetoedException

Syntax

void MarkReadOnly(object entity);

Example

Employee employee = session.Load<Employee>("employees/1");
session.Advanced.MarkReadOnly(employee);
session.SaveChanges();
