Entity Framework Extensions BulkOperationExecuting

The BulkOperationExecuting event is executed before the action in the BulkOperations library is called.

The following example updates the Description and IsActive properties before data is saved to the database in the BulkSaveChanges method.

using (var context = new EntityContext())
    context.BulkSaveChanges(options => 
        options.BulkOperationExecuting = bulkOperation => 
            list.ForEach(x =>  
                x.Description = "Before_Execution_Description"; 
                x.IsActive = false;

Try it in EF6 | Try it in EF Core

The BulkOperationExecuting is updating the Description and IsActive in the list of customers but not in the database.
