Session: How to Ignore Entity Changes

In order to mark an entity as one that should be ignored for change tracking purposes, use the IgnoreChangesFor method from the Advanced session operations.

Unlike the Evict method, performing another Load of that entity won't create a call to the server.

The entity will still take part in the session, but will be ignored for SaveChanges.

Syntax

void IgnoreChangesFor(object entity);

Example

Product product = session.Load<Product>("products/1-A");
session.Advanced.IgnoreChangesFor(product);
product.UnitsInStock += 1; //this will be ignored for SaveChanges
session.SaveChanges();
