How to update value to null using FluentMigrator

How can I update all rows to null using FluentMigrator fluent syntax? You cannot assign null to anonymous type property.

Update.Table("mytable").Set(new { supplierid = null }).AllRows();

I found the answer to my question. You must use DBNull.Value .

Update.Table("mytable").Set(new { supplierid = DBNull.Value }).AllRows();
