SQL Source Control v3.0.5.7 includes a mechanism to allow comparison options to be configured, including ‘Ignore Extended Properties’. To get this version, please run Check For Updates from the Help menu in SQL Source Control.

Comparison options can now be set via a configuration file in your database repository’s Working Base folder. The following article describes how to configure this option: http://www.red-gate.com/SupportCenter/GeneralContent/knowledgebase/SQL_Source_Control/KB201202000521

Our plan in the future is to provide an options dialog to allow users to configure the comparison options that are changed most often, but we believe this configuration file procedure should help users in the interim.

If you’d like to see an options dialog exposing these settings in SQL Source Control, please vote on the following idea – https://redgate.uservoice.com/admin/forums/39019-sql-source-control/suggestions/2615460-add-an-options-dialog-to-allow-configuration-of-co – and let us know which options you’d like to see exposed in the dialog.

Currently, there is not an option to ignore extended properties in SQL Source Control.

This option exists in SQL Compare, so if you use SQL Compare to deploy your db to Test/Staging/Production environments, you can ignore extended properties when you do the comparison and synchronization.
