Even more reflection :)</p> <pre><code> public static void SetSchemaValue(this object obj, string schema) { var mapping_ref = obj.GetType().GetField("mapping", BindingFlags.Instance | BindingFlags.IgnoreCase | BindingFlags.GetField | BindingFlags.NonPublic).GetValue(obj); var mapping = mapping_ref as ClassMapping; if (mapping != null) { mapping.Schema = schema; } } public void Apply(FluentNHibernate.Conventions.Instances.IClassInstance instance) { var schema = instance.GetPrivatePropertyValue<string>("Schema"); if (schema == null) { instance.Schema("My_New_Schema"); } else { instance.SetSchemaValue("My_New_Schema"); } } </code></pre>
