When you are developing code, consider some of these suggestions for the most efficient
performance.  
Importante:  
Starting with the Xanadu release, the legacy version of ServiceNow Studio is being prepared for future deprecation. It will be hidden and no longer activated on new instances but will continue to be supported. For details on the deprecation process, see the [Deprecation Process \[KB0867184\]](https://support.servicenow.com/kb_view.do?sysparm_article=KB0867184) article in the Now Support Knowledge Base.

Try building and editing apps in the current version of ServiceNow Studio instead. For more information, see [ServiceNow Studio](https://servicenow-prod.fluidtopics.net/HJE5fDsb~bjmVZ9BqGtS8w "ServiceNow Studio provides a unified experience for all ServiceNow development activities, enabling admins and developers to extend base system solutions and create custom apps with ease. Use ServiceNow Studio to build apps and app files with integrated tools, access and edit app metadata in scoped and global apps, and package app changes for deployment, all in one powerful development tool.").  

Production instances shouldn't publish to the Git repository
:   To protect the integrity of production, you shouldn't push changes to publish to the Git
    repository from production even though technically you can open and commit changes in the
    application in ServiceNow®
    Studio. The "Can Edit Application in Studio" option can be disabled in
    production on the sys_app record. But it resets at the next source code
    operation that triggers an update (that is, when you apply remote changes or switch branches).

Dependencies are not installed when installing an application from the Git repository
:   Source-controlled applications do not automatically install or upgrade if they are listed
    as the dependency of your application. Instead, the customer must install or upgrade the
    source-controlled application on its own. The customer is also responsible for installing and
    upgrading the applications in the correct order.

Tight control on source control privileges in production
:   The source code operations are generally available to those with development privileges in
    the instance. Since production environments shouldn't have ongoing development, be sure to
    tightly control admin and delegated development privileges to avoid data loss and other
    serious consequences.
