Breaking changes for Customized Commerce 14

Breaking changes for upgrading from Optimizely Customized Commerce 13 to Customized Commerce 14.

Commerce Admin user interface replaces Commerce Manager

The Commerce Administration view is an administrative application replacing the legacy Commerce Manager administration backend system. The new user interface provides a unified and improved user experience.

The Admin view provides support for working with markets, warehouses, catalog indexing, tax configuration, shipping, and payments.

Due to the removal of Commerce Manager, ​the following tasks are now managed through the API:

The Mediachase.BusinessFoundation assembly was also removed as it was mainly used to support Commerce Manager.


Support for the various configuration files in the Configs project folder was removed. The functionality was replaced with the use of Options classes, where you can configure settings in the appSettings file or use the ConfigureServices of the Startup class to override default values for Options. This provides a unified way of configuration methods in ASP.NET Core. See Option configuration classes.

Membership Provider not supported

The support for ASP.NET Membership Provider was removed. Only ASP.NET Identity Provider is supported for Optimizely Customized Commerce. See Security and Migrating from SQL membership to ASP.NET identity.


Mediachase.Commerce.Plugins.Payment was removed because it does not support AuthorizeNet. The library is no longer supported in ASP.NET Core.

Support for payment providers PayPal, DIBS, Datacash, and gift card was removed. The CreatedCardPayment class was marked as obsolete and will be removed later. It is strongly recommended that you adopt a PCI-compliant solution for managing payments in your project.

Solr search providers not supported

Support for Mediachase.Search.Solr35SearchProvider and Mediachase.Search.SolrSearchProvider packages has been removed. As a replacement, you can use the LuceneSearchProvider or FindSearchProvider. There is in-built support for FindSearchProvider in the Optimizely DXP cloud service environments. See Search.

OleDb import parser removed

The Mediachase.MetaDataPlus.Import.Parser.OleDbIncomingDataParser has been removed, and parsing of files using OleDb connection is not supported. CSV and XML data parsers are still supported.

UserTimeZone not supported

The UserTimeZone functionality was removed from Mediachase.BusinessFoundation.Data to avoid dependency on Windows OS.

Webservice support for catalog system removed

You can no longer access the Catalog subsystem through web service calls.

Synchronous execution of events

The following changes were done:

  • ReportingOrderEventListener executes the listeners synchronously.
  • On MetaDataChanged events, the synchronization with the content type model repository is done synchronously.

Binary serialization not supported for ASP.NET Core types

Some ASP.NET Core built-in types are no longer binary serializable. NumberFormatInfo is one example. Since serializable Customized Commerce types like Money and Currency use NumberFormatInfo, these also become unserializable. This is considered a breaking change for solutions that rely on binary serialization of these types, meaning that probably SerializationExceptions is thrown.

Removed APIs

  • Mediachase.Commerce.Engine.Template and Mediachase.Commerce.Engine.Image have been removed.
  • Since HttpModules are not supported in .NET core. EPiServer.Business.Commerce.HttpModules.ProfileModule has been removed.
  • The upgrading migration steps MigrateAdminsRoleStep, PopulateUserPermissionStep, and UpdateContactUserIdStep were removed, and you should upgrade your solution to Commerce version 13 before upgrading to version 14.

Upgrading support

To make upgrading easier, there is an upgrading tool available. See the Upgrade assistant article.
